ABB AC500 PLC - Intended Purpose; Functionality; Electrical Connection

4 Allocation of signal name
5 Terminal block for input signals (9-pin)
6 Terminal block for input 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 group-wise electrically isolated from each other.
The other electronic circuitry of the module is electrically isolated from the inputs.
The I/O module must not be used as a decentralized I/O module with CI590-
CS31-HA bus modules.
Functionality
