The ROI-XMA series is a versatile family of loop powered 4-20mA potentiometer transmitters. Versions can be provided for Base Resistance, between 1K and 10Kohm impedance. Signal range can be custom scaled to alternate resistance spans within sensor range. Transmitter supply voltage may be from 7.5 to 36Vdc. Output circuit is reverse connection protected and filtered.

Use spare PLC 4-20mA inputs for position sensor measurement, with the ROI-XMA potentiometer transmitter. ROI-XMA potentiometer transmitters allow the simple measurement of industry standard potentiometers. Existing 1K ohm NTC thermistors can be connected to modern control systems. The thermistor is a simple way to add temperature sensor measurement to a PLC. The potentiometer is ideally suited for position measurement more simply than other position sensors. Useful in HVAC systems, refrigeration systems, chillers, environmental monitoring, computer room monitoring, dryer, and other monitoring range applications.
