CAUTION!
Risk of damaging the processor module and the connected modules!
Voltages > 35 VDC (DC variants only) or > 288 VAC (AC variants only) might
damage the processor module and the connected modules.
Make sure that the supply voltage never exceeds 35 VDC / 288 VAC.
CAUTION!
Risk of damaging the processor module!
Excess currents at 24 VDC output (24 VDC processor module variant) will
damage the processor module.
Use an appropriate fuse within 24 VDC input connection.
The 100-240 VAC variant contains an internal power supply with a wide-range input. It provides
a 24 VDC output at the terminals L+ and M which can be used to supply the onboard digital
inputs.
The voltage output at 100-240 VAC variants can provide 180 mA max. The
output is protected against overload by a self-resetting fuse (PTC).
According to IEC 60204-1:2016, where control circuits are supplied from an AC
source, transformers having separate windings shall be used to separate the
power supply from the control supply.
1.2.1.1.5 Onboard I/Os
For connection of the onboard inputs and outputs, both a 9-pin and an 11-pin
terminal block are needed and must be ordered separately. Compatible terminal
blocks can be found in TA563-TA565 terminal blocks
TA565 - Terminal Blocks” on page 1164.
The processor module PM55x provides 8 onboard digital inputs (24 VDC) and 6 onboard digital
outputs (depending on variant 24 VDC transistor outputs or relay outputs).
Numbers and types of the onboard I/Os are listed in the table below:
