Thermocouple/Millivolt Input Module
Description
The SNAP-AITM-8 and SNAP-AITM-8-FM modules
provide eight channels of analog to digital conversion.
Each channel on the module can be configured for -75
mV DC to +75 mV DC, -50 mV DC to +50 mV DC, -25
mV DC to +25 mV DC, or for type B, C, D, E, G, J, K, N, R,
S or T thermocouple operation.
Since all inputs share the same reference terminal, use
isolated probes for thermocouple inputs. See the
dimensional diagram on
SNAP-AITM-8 and SNAP-AITM-8-FM
Thermocouple Polarity and Range
NOTE: For best accuracy, wire all points before
calibrating, and short all unused channels.
The SNAP-AITM-8-FM is Factory Mutual approved.
