Potentiometer 4-20mA Transmitters
Read potentiometers with your PLC and potentiometer 4-20mA transmitters
Do you have a PLC and need to read position? Did you know, you can use spare PLC 4-20mA inputs for position sensor measurement? You can add position measurement to a PLC with ROI-XMA sensor transmitters. ROI-XMA potentiometer transmitters allow the simple measurement of industry standard potentiometers. You can easily use potentiometer position sensors to read position with you PLC systems.

4-20mA transmitters are simple to use
Potentiometer 4-20mA transmitters are a simple way to add position measurement to a PLC. Most installers appreciate how potentiometers don’t require you to use special transformers to connect them like LVDTs. All you need is standard instrumentation cable, the sensor, and the transmitter. A potentiometer is integral to many industry standard position sensors.
4-20mA transmitters can be connected long distances
You can connect 4-20mA transmitters can be over long distances to the PLC. When you use a standard 24Vdc power source and a 22Awg cable can connect a 4-20mA transmitter over 1,000 feet away. You could be surprised how rapidly the length of a cable increases, when you try to run it neat and out of the way.
4-20mA transmitters are inexpensive
Potentiometers are inexpensive and are not polarity dependent. With that, you can easily connect and replace them if damaged. A potentiometer is a resistive device. You can easily verify it working with a standard ohm meter and manual position change by adjusting it, which is a great feature.
