The ROI-XMA series is a simple to use family of loop powered 4-20mA potentiometer transmitters. Available in a number of ranges (e.g. 0 to 10K ohm range input and 4-20mA output). 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 or level measurement, with the ROI-XMA potentiometer transmitter. The ROI-XMA potentiometer transmitter allows the simple measurement of industry standard potentiometers. Existing potentiometers can be connected to modern control systems. The potentiometer is a simple way to add position or level measurement to a PLC. temperature range applications.
