CAUTION!
Risk of damaging the AC500-eCo V3 processor module and the connected
modules!
Voltages > 30 VDC might damage the processor module and the connected
modules.
Make sure that the supply voltage never exceeds 30 VDC.
CAUTION!
Risk of damaging the AC500-eCo V3 processor module!
Excess currents at 24 VDC output (24 VDC processor module variant) will
damage the processor module.
Use an appropriate fuse

6.5.3.2 Processor module interfaces
The I/O bus is not available for PM5012-T-ETH and PM5012-R-ETH. I/O
channel extension using option board slot only.
The I/O bus is the I/O data bus for the I/O modules. Through this bus, I/O and diagnosis data
are transferred between the processor module and the I/O modules. Up to 10 I/O modules for
PM5032-x-ETH (but with a limit of 128kB input/ 128KB output variables) and 10 I/O modules for
PM5052-x-ETH and PM5072-T-2ETH can be added.
Depending on the processor module variants, additional option board can be connected to the
option slot to extend the feature of the processor module.
RS232 communication interface is available by using option board:
● TA5141-RS232I (isolated)
Ä
Chapter 6.2.4 “TA5141-RS232I - RS-232 serial adapter isolated option board”

RS485 communication interface is available by using option boards:
● TA5142-RS485I (isolated)
Ä
Chapter 6.2.5 “TA5142-RS485I - RS-485 serial adapter isolated option board”
on page 128
● TA5142-RS485 (non isolated)
