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.

SNAP-AITM-i
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.
