Analog Input Module 07 AI 91
8 inputs, configurable for temperature sensors or as voltage inputs, 24 VDC, CS31 system bus
Intended Purpose
The analog input module 07 AI 91 is used as a remote module on the CS31 system bus. It uses one module address (group number) in the word input range. Each of the 8 channels use 16 bits. The unit is powered with 24 V DC. The CS31 system bus connection is electrically isolated from the rest of the unit. The module offers a number of diagnosis functions. The diagnosis functions perform a self-calibration for all channels.
