NOTICE!
Risk of damaging the PLC modules!
Overvoltages and short circuits might damage the PLC modules.
–
Make sure that all voltage sources (supply voltage and process supply
voltage) are switched off before you begin with operations on the system.
–
Never connect any voltages or signals to reserved terminals (marked with
"NC"). Reserved terminals may carry internal voltages.
The device is used as an optional I/O extension module for AC500-eCo V3 CPUs (PM50x2).
The inputs/outputs are group-wise galvanically isolated from each other.
All other circuitry of the module is galvanically isolated from the inputs/outputs.

Internal power supply
Via internal CPU connection
External power supply
Via the terminals ZP and UP (process supply
voltage 24 V DC)
For a detailed description of the mounting, disassembly and connection of the
module, please refer to the system assembly chapter.
The connection is carried out by using a removable 7-pin terminal block. For more information,
please refer to the chapter terminal blocks for AC500-eCo V3 system. The terminal blocks are
included in the module's scope of delivery and additional terminal blocks as spare parts can be
ordered separately.
The following block diagram shows the internal construction of the digital inputs and outputs:
