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.
Digital configurable input/output unit.
● 8 digital inputs 24 V DC in 1 group (1.0...1.7)
● 8 digital relay outputs with one change-over contact each (R0...R7). All output channels are
galvanically isolated from each other.
● Fast counter
