Description

The 190900B-02 cFP-TC-125 is a 16 bit Thermocouple Input module with a maximum input voltage of 250V common mode, designed by National Instruments for their Compact FieldPoint system. Part number 777318-125, this temperature input module features built-in linearization and cold-junction compensation for eight different types of thermocouples and can be easily mounted on a cFP-BP-x or cFP-180x Compact FieldPoint backplane for effective functionality.

The 190900B-02 cFP-TC-125 is a 16 bit Thermocouple Input module with a maximum input voltage of 250V common mode, designed by National Instruments for their Compact FieldPoint system. This temperature input module, part number 777318-125, can be easily mounted on a cFP-BP-x or cFP-180x Compact FieldPoint backplane to receive power and function effectively. It features built-in linearization and cold-junction compensation for eight different types of thermocouples: B, J, E, R, K, S, N, and T. The cFP-TC-125 also comes with a cFP-CB-x Connector Block for easy connections to the eight differential input channels. Users are advised not to connect anything to the V and C terminals on the connector block. Each channel on the module can handle up to ±250 V common-mode voltage as referenced to earth ground, but the difference in common-mode voltage between any two channels should not exceed 250V. Input signals should be linked to the IN(+) and IN(-) terminals within the voltage input range of -20 to 80 mV to avoid out of range errors. In case of an open thermocouple, the module will display an Open thermocouple error for the corresponding channel and light up the red LED.
