RTD 4-20mA 2 wire loop powered transmitter
The ROI-XMA series is a versatile family of loop powered 4-20mA RTD transmitters. They are simple to use and simple to install RTD temperature sensor amplifiers. Pluggable connections and pluggable mounting. Unit is purchased scaled ready to use, RTD temperature is converted to 4-20mA. Can be used with: data acquisition systems, PLC systems, SCADA systems, and more.
Versions can be provided for 100 ohm PT100 and 1K ohm PT1000 RTDs. Signal range can be custom scaled to alternate RTD temperature spans within sensor range.
MOUNTING: 35mm DIN rail or surface mountable snap on base
SUPPLY RANGE: 7.5 TO 36Vdc, reverse connection protected
SIGNAL OUTPUT: 4-20mA ( LOOP POWERED )**
CONNECTIONS: 30-12awg wire
INPUT RANGE: -200 to 500 Deg C
INPUT TYPE: 100 ohm PT100 or 1K ohm PT1000 RTD, as ordered
DIMENSIONS: 4.510 X 1.258 X 3.948 (height above rail) LWH***
* Loop termination resistor required when used with voltage ADC
** 4-20mA signal uses a 2 wire connection. Resistance transmitter output is connected in series, with supply and measurement device.
*** Mated connector adds additional 3/8” to height.
Use spare PLC 4-20mA inputs for temperature measurement, with the ROI-XMA RTD transmitter. ROI-XMA RTD transmitters allow the simple measurement of industry standard RTDs. Existing 100 ohm PT100 and 1000 ohm PT1000 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 limited 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 limited temperature range applications.
