National Instruments cFP-TC-120 Thermocouple Input Module

The National Instruments cFP-TC-120 (Part Number: 777318-120) is an 8-Channel Thermocouple Input Module. This model comes with integrated cold-junction compensation and linearization for eight types of thermocouple:  B, E, R, K, J, N, T, and S. The NI cFP-TC-120 comes featured with open-thermocouple detection mechanism and indicator LEDs. This module offers 2,300 Vrms overvoltage protection for transients between the I/O channels and the inter-module communication bus. The cFP-TC-120 can easily be mounted on a FieldPoint backplane since it is a hot plug-and-play type of device. Therefore, it can be installed without disturbing the operation of any already operating connector blocks or modules.

This module has a broad -40 to 70° C operating temperature range, which makes it an appropriate choice to be utilized in several applications. Also, it has a recommended storage temperature range of –55 to 85 °C. This model offers 16-bits resolution and features an integrated 50/60 Hz noise filter as well. The NI cFP-TC-120 is a versatile temperature input module for Compact FieldPoint that can be used to measure 2-3,3-, 4-Wire RTDs, thermistors, thermocouples, and millivolt-level voltages. This model comes with significant capabilities; thus, it is considered a reliable solution for temperature monitoring/controlling related applications, including device testing, temperature chamber controlling, and process controlling. The device has a weight of 3.7 oz, with the dimensions: 5.0 x 3.5 x 1.0 in. It has four input voltage ranges: ±25, ±50, ±100, and –20 to 80 mV. With this module, the user can receive readings in three ranges: –454 to 3,218 °F, 0 to 2,048 K, and –270 to 1,770 °C.

To ensure reliable and accurate analog measurements, the cFP-TC-120 has a NIST-traceable calibration certificate. This model offers 250 Vrms common-mode isolation between all modules and channels. Also, this model provides double insulation for operational isolation up to 250 Vrms. The National Instruments cFP-TC-120 can be safely utilized with the cFP-CB-1 or 3 connector block in potentially hazardous applications. The device has an input bandwidth of 3 Hz, an overvoltage protection of ±40 V, an input current of 35 nA typ, 140 nA max, and an input noise of ±1 LSB peak-to-peak.

The cFP-TC-120 is available to be calibrated. While the recommended calibration period for individual parts varies, most parts should be calibrated either annually or every two years to ensure accuracy. If you need the cFP-TC-120 calibrated, Apex Waves provides options. We offer high-quality NIST accredited calibrations through a 3rd party, with an average turnaround time of 1 to 2 weeks. When you order the cFP-TC-120 with us, you can request basic (unaccredited) in-house calibration that will calibrate the part to the manufacturer specifications prior to being shipped.
