The ROI-XMA series are simple to use loop powered 4-20mA PT100 & PT1000 RTD temperature transmitters. Available in a ready to use ranges (e.g. PT100 -200 to 500 Dec C range input and 4-20mA output). Signal range can be custom scaled to alternate RT temperature 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 temperature measurement, with the ROI-XMA thermistor transmitter. The ROI-XMA RTD transmitter allows the simple measurement of industry standard RTDs. Existing 100 or 1000 ohm Platinum RTDs can be connected to modern control systems. The RTD is a simple way to add temperature measurement to a PLC. The RTD is ideally suited for moderate temperature ranges can be used to achieve higher precision than other temperature sensors. Useful in HVAC systems, refrigeration systems, chillers, environmental monitoring, computer room monitoring, dryer, and other moderate temperature range applications.
