ABB AC500 V3 Hardware Manual page 151

1 I/O bus
2 16 yellow LEDs to display the states of the inputs/outputs C0 to C15
3 Terminal number
4 Allocation of signal name
5 Terminal block for input and output signals (9-pin)
6 Terminal block for input and 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
iInterface modules (e. g. CI592-CS31, CI501-PNIO, CI541-DP, CI581-CN) or as a centralized
extension module for AC500 CPUs.
The inputs/outputs are group-wise galvanically isolated from each other.
All other circuitry of the module is galvanically isolated from the inputs/outputs.
2022/01/31
The I/O module must not be used as a decentralized I/O module with CI590-
CS31-HA communication interface modules.
