The WRC1361 is an integrated hybrid component used to sense ambient temperature. It is the component used in WRC 1781 and 1782 Series 5Bxx analog mounting boards to provide cold-junction compensation for the 1781-5B37 and 1781-5B47 thermocouple input modules. When connected in a mounting board with the above 1781-5B thermocouple modules, the voltage output of the sensor is: V1-2 = 0.510 – 0.0025 * (T-25) volts V1-2 is the voltage measured from pin 1 to pin 2 and T is the ambient temperature in Centigrade.
The accuracy of the WRC1361 is:
+5°C to +45°C: 0.7°C
+0°C to +60°C: 1.0°C
