1 I/O bus
2 Allocation between terminal number and signal names
3 4 yellow LEDs to display the states at the inputs I0 to I3
4 4 yellow LEDs to display the states at the inputs I4 to I7
5 1 green LED to display the process supply voltage UP
6 2 red LEDs to display errors (CH-ERR2 and CH-ERR4)
7 Label
8 Terminal unit
9 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).
