REVO PB Power Network with 3 channels

A basic system consists of a single three-channel module, each having the same single-phase connection. Using at least three REVO PB modules for a total of 9 power channels you can balance all three phases. For example: 3x Phase R to Phase S Channels; 3x Phase S to Phase T channels and 3x Phase R to Phase T channels.

At every channel/zone point you can connect a single-phase load with a maximum 35A / 50A / 75A / 90A with a connection Phase to Phase or Phase to Neutral.

Ready for Industry 4.0

We choice Modbus RTU as the standard communication protocol on our units due to the great ease of interfacing with other industrial equipment such as HMI operator panels, PLCs, industrial PC’s, and other units present on the system as in most cases are already equipped with this communication standard.

Using the TU-RS termination unit you can connect the REVO PB with some of the most common field bus systems including PROFINET, PROFIBUS DP, EtherNet IP & # x2122 and Modbus TCP.

Each unit is supplied as an easy to install plug and play device, helping you get up and running as quickly as possible.

Optimisation of Energy

Poor management and the addition of unsynchronised loads can lead to an increase in the generated harmonic component (THD). This effect increases losses, generates noise and can generate overheating of power cables.

Even by using Zero Cross firing and a non-continuous operation, the harmonic components can reach critical levels.

Thanks to its control strategy and the management & distribution of power throughout the multi-zone loads, REVO PB keeps the Power Factor value close to 1 (a near perfect value).

A high-Power Factor, a low waveform distortion and a decrease in harmonic components, will lead to a reduction in the cost of energy used.

ifm launches easy-to-use humidity sensor

Easy to install and requiring no user set up, humidity sensors in the new LDH29x range from ifm electronic provide a convenient, reliable, and cost-effective method of monitoring humidity and temperature levels in control panels and other items of sensitive electrical and electronic equipment. This is particularly useful for equipment such as vending machines and ticket issuing machines which are often installed in outdoor locations where they are exposed to weather and fluctuating levels of ambient moisture.

The sensors, which feature compact construction and are suitable for surface or DIN-rail mounting, can also be used to provide accurate humidity and temperature information for control purposes in moisture-sensitive manufacturing processes.

Two versions of ifm’s new humidity sensors are available. The LDH290 version provides two conventional 4 to 20 mA analogue outputs, while the LDH292 version provides a digital IO-Link output that ensures accurate data transmission irrespective of the length of the connection between the sensor and its associated control system.

Both versions provide an output of 0-100% RH whilst the temperature sensor has a range of -40 to +60 ºC for analogue types and -40 to +80 ºC for IO-Link types

Electrical connections to LDH29x humidity sensors use a standard M12 connector, and ifm offers a full range of compatible ready-terminated connecting cables as optional accessories.

Moore Industries Rugged, Reliable, and Versatile Frequency-to-DC Transmitters

Moore Industries offers two highly reliable and rugged instruments to monitor frequency, period, high or low pulse width, and contact closure signals for a wide range of industries including oil and gas, chemical, power generation, pulp and paper, nuclear remediation and petrochemical. The SFY Functional Safety Frequency-to-DC Transmitter and the FDY Frequency-to-DC Transmitter are PC-Programmable field devices that convert frequency related input signals to an isolated and proportional 4-20mA output signal ready for direct interface with a Safety System, recorder, PLC, DCS, SCADA system or other readout instruments.

SFY Functional Safety Frequency-to-DC Transmitter with Display
As part of Moore Industries FS Functional Safety Series, the 2-wire (loop-powered) SFY  has been certified by exida to ensure conformance with strict IEC 61508:2010 standards for safety-related applications and is approved for single use in Safety Instrumented Systems (SIS) up to SIL 2 and in a redundant voting architecture (1oo2, 2oo3, etc.) up to SIL 3. This makes the SFY ideal for use in Safety Instrumented Functions (SIF) where frequency or pulse signals need to be monitored. Examples of this include turbine over speed protection, critical exhaust fans for personnel safety, compressor monitoring and protection (FMEDA reports are available with the required safety data to ensure that the SFY meets the requirements of each SIF).

Customers will find the SFY ideal for use in a wide variety of process related safety applications that utilize turbine flow meters, magnetic pickups, dry contact closures, variable frequency drives, turbine tachometer generators, rotating equipment, motor and conveyor speed as well as pulse and frequency output transducers. The SFY helps provide over speed protection by sending signals that warn the SIS logic solver to alarm or shut down the monitored device for plant, personnel, or process protection.

Compressor Monitoring and Protection
Industrial compressors are often used in large facilities to supply headers with air for pneumatic instruments and valves. These compressors must run at precise speeds, and if they start to run too fast, the compressors can become very dangerous and expensive to repair when they are damaged. This means that many of these critical compressors require an independent safety protection system or SIF.

The SFY can be used as part of the SIF to monitor compressor speed and provide data to a safety logic solver. To accomplish this, a magnetic pickup is often attached to the compressor shaft. This pickup provides a frequency output which the SFY converts to a 4-20mA output proportional to the compressor shaft speed and is shared with a SIS Logic Solver. Should there be a situation where the compressor reaches an overspeed or unsafe event, the logic solver can take the necessary action to avoid potentially dangerous situations and costly repairs.

FDY PC-Programmable Frequency-to-DC Transmitter with Display
When Safety Instrumented Systems and SIL ratings are not a requirement, the 2-wire (loop-powered) FDY is also a great solution for use in a wide range of process and factory automation applications that require the monitoring of turbine tachometer generators, turbine flow meters, magnetic pickups, dry contact closures, variable frequency drives, rotating equipment, pulse and frequency output transducers, and motor and conveyor speed. The FDY has worldwide hazardous area approvals and sets up in just minutes with PC programming software.

Make Consistent Flow Measurements
When making flow measurements with turbine flow meters, one common source of measurement inconsistencies is frequency variation due to bent blades. The FDY incorporates a programmable moving average filter to compensate for the bent blades. The user-selectable moving average is set to match the number of turbine blades; the FDY then takes a reading from each blade and averages the readings to produce a “smoothed out” 4-20mA value proportional to the continuous averaged measurement. This advantage stretches the time between maintenance cycles needed to replace the rotor in the turbine meter by delivering accurate measurements even if turbine blades are damaged.

Both the SFY and FDY Frequency to DC Transmitters include 5-digit LCD displays which show the process variable in selectable engineering units for easy viewing. They provide exceptional accuracy at +/-0.025% of span and long-term stability with up to five years between scheduled calibrations. These instruments also have versatile input choices, measuring frequency ranges between an impressively low 0.005Hz up to 25kHz; periods from 40microseconds to 200sec; and pulse widths from 0.2msec to 200 seconds. They are RFI/EMI protected and programmable in just minutes with PC software.

The Technology Behind the M81-SSM’s Precise Signal Synchronisation

One of the most unique features of the new modular Lake Shore MeasureReady™ M81-SSM synchronous source measure system is its patent-pending MeasureSync™ signal synchronisation technology. This real-time sampling architecture enables simultaneous source module update and measure module sampling timing across all channels, regardless of signal types for frequencies up to 100 kHz.

Because MeasureSync samples all channels at precisely the same time, it ensures that multiple devices under tests (DUTs) are tested under identical conditions, so you obtain consistent measurement data. In addition, the architecture allows each source and measure amplifier module to be physically co-located as near as possible to the DUT to further minimise noise pickup from ambient, thermal, ground loop, and other common interference sources.



Amplitude and frequency signals are transmitted to/from the remote amplifier modules using a proprietary, real-time analogue voltage method that minimises noise and ground errors while ensuring tight synchronisation of all modules. This analogue interface keeps noisy digital circuitry away from the modules’ sensitive analogue circuits. The signals are digitised by a dedicated converter for each channel, which are synchronised by the shared MeasureSync clock. Each rising edge of the clock triggers every ADC to take a reading and triggers each DAC to update its output. In between clock edges, all of the data is transferred from ADCs to the controller and each DAC is preloaded with a value that is applied on the next edge. Unlike multiplexed systems, this maintains total synchronisation and continuous sampling of each channel. Digital signals are generated or processed by a configurable DSP core.

Each measure channel can be configured to perform DC, AC, or lock-in measurements. The core processes the individual readings collected at 375 kSa/s and produces fully processed and calibrated readings at up to 5 kSa/s. These readings can be observed on the front panel and collected via the remote interface.

The multiple parameter query structure allows a single data query to return multiple readings in one query, which maintains synchronisation. Additionally, the configurable data streaming interface can be used to provide a continuous stream of synchronised data at a fixed, regular time interval, or a burst of high-speed collection. This combination of an analogue interface to the distributed modules, a centralised simultaneous acquisition clock, and a unified remote interface provides end-to-end signal synchronisation that cannot be easily achieved with separate instrumentation.

The Lock-in Amplifier Explained and Reimagined

Measurement of electrical signals, voltage, and current is one of the most important methods used by researchers to characterise electronic materials. But electrical signals are often at very low levels and in the presence of noise — which can be as large as or even larger than the signal itself.

Because DC measurement instruments cannot easily extract the signal from the noise, AC measurement techniques are often used. They can modulate the signal with a frequency to measure the signal in the presence of less noise. The lock-in amplifier can perform such a measurement and is one of the best methods for measuring amplitude and phase of AC signals. For these reasons, it is the instrument of choice for low-level measurements of AC signals.

The new app note discusses lock-in amplifiers in general and examines how the lock-in technology employed in a new, modular source measure architecture deals with removing the effects of noise from the measurement. It details how the new M81-SSM architecture offers:

  • Filters designed to remove noise and decrease measurement time
  • Multiple measure options, with the flexibility of measurement configurations
  • Multiple source modules, which can be matched to measurement requirements

SICK’s Mini InspectorP611 Packs in Machine Vision Power

SICK has launched an ultra-compact and ultra-powerful all-in-one 2D vision sensor, the InspectorP611, which can be set up rapidly to conduct highly-reliable inline machine vision inspections even in the tightest of machine spaces, or when mounted on robot arms.

With the SICK InspectorP611 2D vision sensor and pre-installed Quality Inspection SensorApp, users rapidly configure inline inspection, part localisation and measurement tasks to run automatically on the device.

Small enough to be mounted right where it is needed inside a machine, the InspectorP611 is ideal for measuring or verifying the finer details of small assemblies, electronics components or glue beads, for example. Tiny and lightweight, it can also be mounted on robot arms to provide real-time quality checks and positioning for tasks such as the insertion of small screws.

Rapid Installation and Configuration

Following instant installation with snap-in mounting, users quickly obtain high-quality images ‘out of the box’ with the SICK InspectorP611’s integrated optics and adjustable LED illumination. Simply connect the SICK InspectorP611 to a PC with a standard web-browser interface to configure a wide choice of machine vision tools to run directly onboard the camera, sufficient to set up most applications in no time. Additional flexibility is also built-in to expand or customise inspections, together with the option to progress with ease to SICK’s Intelligent Inspection Deep Learning SensorApp for more challenging inspections, when required.

It might be the smallest of the InspectorP600 family of programmable 2D vision sensors, but the SICK InspectorP611 packs the power of its larger siblings into a miniature device that fits in the palm of your hand,” said Neil Sandhu, SICK’s UK Product Manager for Imaging, Measurement and Ranging.

Whether you are a novice or an expert, it is quick and easy to configure your machine vision application using the onboard image processing tools provided within the SICK Quality Inspection SensorApp. It’s also simple to download additional free tools for specific applications, such as glue bead inspection, while more experienced users have the flexibility via the programming interface to access time-saving, ready-made code so they can fast-track customised inspections. Meanwhile even inexperienced users can progress to Deep Learning, starting from a low cost of ownership.”

High Quality Image Processing with Flexible Illumination

The SICK InspectorP61x is a versatile 2D vision sensor just 50 x 40.3 x 29.6 mm in size. It processes high-quality images with up to 1.2 Mpixel resolution, ideal for small- and medium-sized objects, even at very short distances down to 50mm. Its built-in illumination assures optimum results even at tight angles and supports reliable inspection all the way up to 300mm, enabling a much larger field of view when required.

In-situ camera set-up time is minimal, thanks to a choice of 6mm or 12mm pre-installed lenses, together with the InspectorP611’s innovative integrated illumination. An array of blue and amber LEDs built into the sensor housing enables the user to fine tune the brightness, colour and shape of the illuminated inspection area to achieve the best possible image processing results.

Pre-installed Quality Inspection Software

In common with all the SICK InspectorP600 family of 2D vision sensors, the InspectorP611 comes with SICK’s Quality Inspection SensorApp already installed. Users are guided through easy point-and-click configuration, and have the freedom to add, combine and customise the machine vision tools they need. With the additional programming flexibility and tools within the SICK AppSpace software platform, users have the option to further extend their applications with minimal coding time, as well as to access the HALCON machine vision library.

Deep Learning Extension Option

Seamless integration with the SICK Intelligent Inspection Deep Learning SensorApp provides users with a rare opportunity using a vision sensor of the InspectorP61x’s tiny size to progress to Artificial Intelligence vision classifications. With the benefit of training a neural network based on real examples, users can try out the suitability of Deep Learning classification for their application before purchasing the additional license required. They can also use traditional rule-based vision tools together with Deep Learning to solve the application.

Image processing is conducted directly onboard the SICK InspectorP611 and the digital input and outputs offer versatile automation options for communication of measurement data to higher-level control systems, as well as for remote diagnostics and process monitoring. Its versatility for many applications is assured by a wide range of communications interfaces via Ethernet TCP/IP, FTP, EtherNET/IP®, and PROFINET fieldbuses.

The bulk of the displays are supplied as a display component to be integrated into your own equipment enclosure, however some display sizes can be supplied within their own industrial enclosure which is designed to be dropped into a cut out in a face plate or fascia.

Full and semi customisation is available across the complete range should you have a specific need that is not covered by the standard specification.

ifm delivers quality control without the cost and complications

The new PMD laser line-scan profilers from ifm electronic offer a convenient, cost-effective and easy-to-use solution to the challenge of inline inspection of components and assemblies to detect manufacturing faults. Much more reliable than manual inspection – yet capable of detecting even small and subtle faults – PMD profilers are a fraction of the price of conventional vision systems and can be configured in minutes using just three integrated pushbuttons – no software is required.

The profilers work by scanning a line across a good sample of the object to be inspected and, using laser time-of-flight technology, storing a profile for this line. Subsequent objects are scanned in the same way and the results are compared with the stored version. If the deviation is greater than a user-definable limit, the profiler’s good/bad output changes state. The evaluation of the profile covers a specific ‘region of interest’ which again is user definable.

Key benefits of this method of operation are that results are unaffected by ambient light levels or by changing distance, over a wide range, between the profiler and the object being inspected. In addition, small faults, such as incorrectly tightening fixings, missing seals and defective or missing machining steps, can easily be detected. The profilers are also invaluable aids for applications such as product sorting and orientation.

Currently, ifm’s PMD profilers are offered in two versions. The OPD100 version allows users to set one region of interest and stores a single profile, while the OPD101 supports two regions of interest and stores up to ten profiles. Both versions offer standard switching outputs together with an IO-Link interface. The use of IO-Link in conjunction with the optional ifm Vision Assistant software package provides additional options, including the capture and display of scanned profiles.
