Description
The part number 777318-125 refers to a component in the Compact FieldPoint category, specifically model cFP-TC-125. This model is described as a cFP-TC-125, 16 bit Thermocouple Input (TC, mV), 250V Common Mode, designed to accommodate various thermocouple types. It supports B, J, E, R, K, S, N, T thermocouple types, offering a versatile solution for temperature sensing in a wide range of applications.
The cFP-TC-125 comes with 8 differential input channels, providing ample connectivity for multiple temperature sensors. These channels are capable of handling a common-mode voltage of ±250 V as referenced to earth ground, ensuring reliable performance even in environments with high voltage interference. The voltage input range of -20 to 80 mV allows for the measurement of small signals typically associated with thermocouple outputs.
Among its notable features, the cFP-TC-125 boasts built-in linearization, cold-junction compensation, and open thermocouple detection. These features enhance the accuracy and reliability of temperature measurements by compensating for potential error sources. Furthermore, the device is compatible with cFP-BP-x and cFP-180x backplanes and cFP-CB-x connector blocks, offering flexibility in system configuration.
Error indication capabilities include out of range error and open thermocouple error, which help in diagnosing and troubleshooting the system effectively. These features ensure that any issues with the thermocouple inputs or the overall system performance are quickly identified and addressed.
