Thermocouple/Millivolt Input Module
Description
The SNAP-AITM 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.
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.
