Intended Purpose

The analog input module AI561 can be used as a decentralized communication interface module at the following devices:

• S500 bus modules (e. g. CI592-CS31, CI501-PNIO, CI541-DP, CI581-CN)
• AC500 CPUs (PM5xx)

It contains the following features:

• 4 configurable analog inputs (I0 to I3) in 1 group

The inputs are not electrically isolated from each other.

All other circuitry of the module is not electrically isolated from the inputs or from the I/O bus.
