The National Instruments SCXI-1112 Thermocouple Input Modules are designed for high-accuracy thermocouple measurements. This module has 8 differential analog input channels and 8 cold-junction sensor channels. This module incorporates open-thermocouple detection circuitry on each input channel.

Each channel on the SCXI-1112 has a 3-pole lowpass filter with a 2 Hz cutoff frequency to reject 60 Hz noise. The number of analog signals that can be digitized is greatly increased by multiplexing several SCXI-1112 modules into a single channel on the DAQ device.
