IC200ALG620 GE Fanuc VersaMax Analog Input Module

Product Description

The IC200ALG620 Analog Input RTD Module is an intelligent module that accepts input signals from up to four RTD input devices and provides input data with 16 bits of resolution.

Host Interface

The RTD Module provides four words of analog input data.

Diagnostics
