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 configuration is performed by software. The modules are supplied with a process supply
voltage of 24 V DC.
All available inputs/outputs are galvanically isolated from all other circuitry of the module. There
is no potential separation between the channels within the same group.
For use in extreme ambient conditions (e.g. wider temperature and humidity range), a special
XC version of the device is available.

Effect of incorrect input terminal con-
nection
The device is plugged on a terminal unit
for I/O modules" on page 126. Position the module properly and press until it locks in place. The
terminal unit is either mounted on a DIN rail or to the wall using 2 screws plus the additional
accessory for wall mounting (TA526
on page 902).
Connections
The connection of the I/O channels is carried out using the 40 terminals of the I/O terminal unit.
I/O modules can be replaced without re-wiring the terminal units.
