SNAP-AITM-2
Thermocouple Polarity and Range
Description
The SNAP-AITM-2 module provides an input range of ±50
mV, ±25 mV, or Type B, C, D, G, N, T, R, or S thermocouple.
Since both inputs share the same reference terminal, use
isolated probes for thermocouple inputs. If you need
isolated channels on the same module, see Opto 22 form
#1182.

C, D, G
R, S
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.
