Description
The SNAP-AITM2-i module provides an input range of ±50
mV, ±25 mV, or Type B, C, D, G, N, T, R, or S thermocouple.
The two channels on the module are isolated from each
other. Since these channels do not share any common
connections, grounded sensors and field devices may be
used with them.

IMPORTANT: The mounting rack connector has 24 pins; the
module connector has 20 pins. The extra pins on the
mounting rack connector prevent misalignment of the
module during installation.
