ABB AC500 PLC User Manual

1 I/O bus
2 Allocation between terminal number and signal name
3 32 yellow LEDs to display the signal states at the digital outputs (O0 - O31)
4 1 green LED to display the state of the process supply voltage UP
5 4 red LEDs to display errors
6 Label
7 Terminal unit
8 DIN rail
Sign for XC version
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 outputs are electrically isolated from all other circuitry of the module. There is no potential
separation between the channels.
