ABB AC500 PLC - Intended Purpose; Functionality

3 Terminal number
4 Allocation of signal name
5 Terminal block for input signals (9-pin)
6 Terminal block for output signals (11-pin)
7 2 holes for wall-mounting with screws
8 DIN rail
Intended Purpose
The device can be used as a decentralized I/O extension module for S500 Communication
Interface Modules (e. g. CI592-CS31, CI501-PNIO, CI541-DP, CI581-CN) or as a centralized
extension module for AC500 CPUs (PM5xx).
The inputs are not electrically isolated from each other.
The outputs are not electrically isolated from each other.
All other circuitry of the module is not electrically isolated from the inputs/outputs or from the I/O
bus.
The I/O module must not be used as a decentralized I/O module with CI590-
CS31-HA bus modules.
