10K Ohm NTC Thermistor to 4-20mA loop powered transmitter

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

• PLUGGABLE EURO ELECTRICAL CONNECTORS

• SNAP ON MOUNTING BASE FOR DIN RAIL OR SURFACE MOUNTING

• WIDE 4-20mA LOOP SUPPLY RANGE FROM 7.5-36V

• USED IN REMOTE MONITORING

• MEASURE 10,000 OHM INDUSTRY STANDARD NTC THERMISTORS

• READ THERMISTOR WITH PLC, RTU, & PC A-D SYSTEMS

• USE WITH 20mA, 5V, & 10V DATA ACQUISITION SYSTEMS *

Specifications:

MOUNTING: 35mm DIN rail or surface mountable snap on base

SUPPLY RANGE: 7.5 TO 36Vdc

SIGNAL OUTPUT: 4-20mA (LOOP POWERED )**

CONNECTIONS: 30-12awg wire

INPUT RESISTANCE RANGE:  50 to 250 Deg F

INPUT TYPE: 10K OHM NTC 2 WIRE THERMISTOR

RESPONSE: <10mS

DIMENSIONS: 4.510 X 1.258 X 3.948” (height above rail) lwh***

* Loop termination resistor required when used with voltage A-D ( ADC )

** 4-20mA signal uses a 2 wire connection. Thermistor 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 thermistor transmitter. ROI-XMA thermistor transmitters allow the simple measurement of industry standard thermistors. Existing 10K ohm NTC thermistors can be connected to modern control systems. The thermistor is a simple way to add temperature measurement to a PLC. The thermistor 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.
