Description
The SNAP-AITM-i module provides two channels of analog to
digital conversion. Each channel on the module can be
configured for -150 mV DC to +150 mV DC or -75 mV DC to
+75 mV DC, or for type E, J, or K thermocouple operation. The
two channels 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.
