Standard – Modified – Customised Automation Electronics since 1988 Electromen manufactures electronic devices for industrial environments and automation solutions. Due to our long experience in industrial electronics engineering, Electromen designers have repeatedly come across the same requirements in signal isolation and conditioning, which is why Electromen has created a growing family of automation modules, that are ready to be delivered from stock. The Electromen automation product family includes products for handling the most common problems and control tasks in industrial...

GALVANIC ISOLATORS / SIGNAL CONDITIONERS

FEATURES: • Three way isolated • Multiple operating ranges • Two frequency ranges • Dip-switch settable • Isolation up to 1000 V • Adjustable zero and gain • Short circuit protected • Rail mountable EM-M11A is a multiscale conditioner and isolator module for the commonly used signals in automation. The range setting is easily done with DIP-switches and signal frequency limit can be set to 1 kHz or 20 Hz. Every partition (INPUT, OUTPUT, SUPPLY) is galvanically isolated up to 1000 V. Gain and Zero are easy to adjust and there is no mutual effect between these adjustments. The number of...

FEATURES: • No supply required • Operation range 0...25 mA • Isolation up to 2000 V • Low voltage drop • Over current protected • Over voltage protected • Incorrect polarity protected • Wide input voltage range • Rail mountable EM-M14 is an easy way to isolate current loop signals obtaining a good accuracy. No additional supply voltage is required. Voltage drop is minimal although the input voltage range is very wide. EM-M14 isolator is effectively protected against misconnections, over voltages and over currents. Output current can also be converted to a voltage signal with the inbuilt 100...

FEATURES: • Eight frequency ranges • Isolated input • High linearity • Various input options • Output signal mA or V • Good output filtering • Output short circuit protected • Adjustable zero & gain • Rail mountable EM-M17b converts applied frequency to 0...10 V or to 4...20 mA signal. Frequency range is selectable with DIP-switches. Converter can be used with most of the commonly available transducer types. Frequency can be applied also as a pulsed voltage signal. The frequency input can be isolated optically if transducer supply and SW1/1 is left open. Converted signal is filtered using a...

FEATURES: • Five different output signals • Supply isolated from signal • Regulated potentiometer supply • For potentiometers 1 ... 47 kohm • Adjustable zero and gain • Short circuit protected output • Rail mountable EM-M19 supplies a regulated voltage for potentiometer. The voltage signal from the potentiometer is filtered and amplified. The output range may be selected from five different alternatives. Output signal is easily set with DIL-switches. The supply is galvanically isolated from the output signal. This permits flexible installation to different systems. The output stage is short...

FEATURES: • Wide operating voltage range • Operates in current loop • Selectable filtering • Adjustable zero and gain • Over voltage protected • Incorrect polarity protected • Easy to connect • Rail mountable EM-M20 converts the position information of a potentiometer to milliampere signal ( 4...20 mA). Converter acquires its operating voltage from the current loop and needs no additional supply. Adjustments have no mutual effect. This makes the adjusting more easy and faster. The filtering can be selected from four alternatives to be suitable for different applications. Versatile...

FEATURES: • Wide operating voltage range • 4...20 mA / 1...5 V output • Multiple ranges • Three wire compensated • Linearisation inbuilt • Adjustable zero and gain • Over voltage protected • Incorrect polarity protected • Easy to connect • Rail mountable EM-M21A is a multiscale converter for thermal transducer Pt-100. Pt-100 transducer is connected to converter with three wires. In this way the cable resistance is compensated. The converter has four selectable temperature ranges and a -50 °C settable offset. The gain and zero adjustments have no mutual effect. The output signal is 4...20 mA...

FEATURES • Measures TrueRMS • Input ranges 5A and 1A • Output 4...20mA and 1...5V • Settable gain • Over current protected • Reverse current protected • Easy to connect • Rail mountable EM-M22 is designed for measuring AC current. The device was designed to work with current transformer and as a converter to current signal. The AC current is measured as TrueRMS, in other words the device gives RMS output also from other than sinus shaped signals. The measured current is converted into 4...20mA signal. There are two measuring ranges, 5A and 1A, which are standard current transformer output...

FEATURES: • Three way isolated • Multiple operating ranges • Also for bibolar signals • DIP-switch settable ranges • Two frequency ranges • Adjustable zero and gain • Isolation voltage 1000 V • Short-circuit protected • Rail mountable EM-M24 conditioning amplifier provides complete galvanic isolation between input, output and supply. Frequency ranges are DIP-switch settable. Input and output ranges can be selected individually. Input filtering can be selected from two alternatives. The effect of zero and gain adjustments is ± 15 % of the selected range. Zero and gain adjustments have no...
