Data Sheet  |   Configure System popup

The National Instruments cFP-TC-125 is an 8-channel input module for direct measurement of temperature from standard J, K, T, N, R, S, E, and B thermocouple types. In addition to double-insulated isolation, input noise filtering, and a high-accuracy delta-sigma 16-bit analog-to-digital converter, the NI cFP-TC-125 also offers 250 V common-mode isolation between channels. With these specifications, the cFP-TC-125 delivers reliable, accurate temperature or millivolt measurements with high common-mode voltage isolation. With HotPnP (plug-and-play) operation, autodetection of modules, self-diagnostics, and automatic scaling to engineering units, the cFP-TC-125 module is easy to install and configure. To ensure measurement accuracy, an onboard microcontroller compensates and linearizes thermocouple readings to the NIST-90 standard, using an advanced linearization routine. The cFP-TC-125 module comes with a NIST-traceable calibration certificate (on request) to ensure accurate, reliable measurements.
