This module is compatible for use with Thermocouple type B, E, J, K, R, S, T, N, C, D, L (TXK/XK). The valid input range for this module is -12 to 78 mV and -12 to30 mV for high resolution range. The module’s resolution is 16 bits with 1.4 ?V/bit (typical) for -12…78 mV and 0.7 ?V/bit High Resolution range for -12…30 mV. Additionally, for -12…30 mV, the Low signal and user counts are 15.80323 mV and -32768 counts while High signal and User counts are 31.396 mV and 32767 counts. For -12…78 mV, Low Signal and User counts are -15.15836 mV and -32768 counts while High signal and user counts are 79.241 mV and 32767 counts.

The module scan time is relatively fast and varies depending on the data format and signal type. For millivolt input, scan time is 25 ms min floating point while 10 ms min for integer. For Floating point format, scan time is 50 ms min.
