National Instruments cFP-TC-125 Temperature Input Module for Compact FieldPoint
The NI cFP-TC-125 (Part Number: 777318-125) can be mounted on a cFP-BP-x or cFP-180x Compact FieldPoint backplane. This results in delivering functioning power to the module. This module has built-in linearization and cold-junction compensation for eight types of thermocouples: B, J, E, R, K, S, N, and T. In addition, the cFP-CB-x Connector Block has connections for the eight differential input channels on the NI cFP-TC-125 module. The user should keep in mind that they should not link anything to the V and C terminals on the connector block.
Each of the eight channels on the cFP-TC-125 Temperature Input Module rejects as much as ±250 V common-mode voltage as referenced to earth ground. However, the user must ensure the difference in common-mode voltage between any two channels does not go over 250 V. To link voltage input signals, the user should link the positive lead of a millivolt signal to the IN(+) terminal and the negative lead to the IN(-) terminal. The voltage input range is from -20 to 80 mV. An input signal not falling within this range will result in the NI cFP-TC-125 module reporting an Out of range error for the affected channel. Additionally, if the user chooses the -20 to 80 mV range for an input channel in software, then choosing a thermocouple type for that channel will not change anything.
The National Instruments cFP-TC-125 Temperature Input Module senses open thermocouples on channels arranged for temperature ranges. When the module notices an open thermocouple, the NI cFP-TC-125 will show an Open thermocouple error for the corresponding channel and will light the matching red LED.

National Instruments cFP-TC-125 Frequently Asked Questions
Question: What is the update period for all channels on the cFP-TC-125 module?
Answer: The update period for all channels on the cFP-TC-125 module is 0.22 s with the filter off and 0.99 s with the filter on.
Question: What is the signal input bandwidth of the NI cFP-TC-125?
Answer: The NI cFP-TC-125 has a signal input bandwidth of 12 Hz.
Question: Which Measurement Category does the cFP-TC-125 belong to?
Answer: The cFP-TC-125 belongs to Measurement Category II, so it should only be used at or below this category.
Question: What is the safety isolation voltage for the NI cFP-TC-125?
Answer: For the NI cFP-TC-125, the continuous channel-to-ground isolation voltage is 250 VRMS, Measurement Category II and the withstand channel-to-ground isolation is 2,300 VRMS, 5 s maximum. There is not a channel-to-channel isolation voltage.
