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.

Wrong or no signal detected, no damage up to 35 V
The device is plugged on a terminal unit
Chapter 1.5.2 “TU515, TU516, TU541 and TU542
. 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
Chapter 1.8.2.6 “TA526 - Wall mounting accessory”
Connections
For a detailed description of the mounting, disassembly and connection of the
module, please refer to the System Assembly, Construction and Connection
Chapter 2.6 “AC500 (Standard)” on page 971.
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.
