Allocation of signal name
5
Terminal block for output signals (9-pin)
6
Terminal block for 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 outputs are group-wise galvanically isolated from each other.
All other circuitry of the module is galvanically isolated from the outputs.

Connections
The connection is carried out by using removable 9-pin and 11-pin terminal blocks. These
terminal blocks differ in their connection system (spring terminals or screw terminals, cable
mounting from the front or from the side). The terminal blocks are not included in the module's
scope of delivery and must be ordered separately.
The following block diagram shows the internal construction of the digital outputs:

The I/O module must not be used as a decentralized I/O module with CI590-
CS31-HA communication interface modules.
Value
For signal states
Via I/O bus
Via the terminals L+ (process voltage 24 V DC) and M (0 V
DC); the M terminal is connected to the M terminal of the CPU
via the I/O bus
For a detailed description of the mounting, disassembly and connection of the
module, please refer to the System Assembly chapter
eCo" on page 925.
