Strain Gage I/O Modules
IC695ALG412 HE693STG883 HE693STG884
Product Name
Isolated Thermocouple Input module
provides twelve isolated differential
thermocouple input channels. Each channel
can be individually configured for inputs from:
Thermocouple types: J, K, T, E, R, S, B, N, or C
and Voltage: ±150mV or ±50mV. Offers a 10 dB
improvement in noise rejection compared to
ALG312 thermocouple inputs.
