RTD 4-20mA temperature transmitters

READ TEMPERATURE SENSORS WITH YOUR PLC

Use spare PLC 4-20mA inputs for temperature sensor measurement, with ROI-XMA RTD transmitters. ROI-XMA RTD transmitters allow the simple measurement of industry standard series 100-ohm PT100 or 1000 (1K) ohm PT1000 RTD temperature sensors. Existing RTD temperature sensors can be connected to modern control systems. An ROI-XMA RTD 4-20mA transmitter is a simple way to add temperature sensor measurement to a PLC.

RTD 4-20mA transmitters are simple to use

ROI-XMA RTD 4-20mA transmitters are a simple way to add temperature measurement to a PLC. Most installers appreciate how RTD don’t require you to use exotic cabling to connect them like thermocouples. All you need is standard instrumentation cable for both the sensor and transmitter.

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.

RTD 4-20mA transmitters are inexpensive

RTDs are inexpensive and are not polarity dependent. You can easily connect and replace them if damaged. An RTD is a resistive device. You can easily verify it working with a standard ohm meter and the heat change by holding it, which is a great feature.
