All inputs (DI0...DI7) belong to 1 group. All outputs (DO0...DO5 / NO0...NO5) belong to 1
group. The inputs and outputs are group-wise electrically isolated.
The processor module PM56x provides 6 onboard digital inputs (24 VDC), 6 onboard digital out-
puts (depending on variant 24 VDC transistor outputs or relay outputs), 2 onboard analog inputs
(voltage 0 V...10 V) and 1 onboard analog output (voltage 0 V...10 V or current 0 mA...20 mA / 4
mA...20 mA). The onboard analog inputs can be configured as digital inputs, so 8 onboard dig-
ital inputs may be available if no analog inputs are needed.
Numbers and types of the onboard I/Os are listed in the table below:

*) PM56x has 2 analog inputs which can be configured as digital inputs. If the analog inputs are
configured as digital inputs, 8 digital inputs are available overall.
All digital inputs (DI0...DI5) belong to 1 group. All digital outputs (DO0...DO5 / NO0...NO5)
belong to 1 group. These inputs and outputs are group-wise galvanically isolated.
The 2 analog inputs are not galvanically isolated from the 24 V power supply of
the processor module.
