4 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
Interface Modules (e. g. CI592-CS31, CI501-PNIO, CI541-DP, CI581-CN) or as a centralized
extension module for AC500 CPUs (PM5xx).
The outputs are group-wise electrically isolated from each other.
All other circuitry of the module is electrically isolated from the outputs.
The I/O module must not be used as a decentralized I/O module with CI590-
CS31-HA bus modules.
Functionality
Parameter Value
LED displays For signal states
Internal power supply Via I/O bus
External power supply Via the terminals L+ (process voltage 24 VDC) and M (0
VDC); the M terminal is connected to the M terminal of the
CPU via the I/O bus
Electrical Connection
For a detailed description of the mounting, disassembly and electrical connec-
tion of the module, please refer to the System Assembly chapter
Ä
Chapter 2.5
“AC500-eCo” on page 1192.
The electrical 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). For more information, please refer to the
chapter Terminal Blocks for S500-eCo I/O Modules

Chapter 1.8.3.2 “TA563-TA565 - Terminal
Blocks” on page 1164. 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:
