Intended Purpose

Processor Module PM56x

The Processor Module PM56x provides 6 onboard digital inputs (24 V DC), 6 onboard digital outputs (depending on variant 24 V DC transistor outputs or relay outputs), 2 onboard analog inputs (voltage 0 … 10 V) and 1 onboard analog output (voltage 0 … 10 V or current 0 … 20 mA / 4 … 20 mA). The onboard analog inputs can be configured as digital inputs, so 8 onboard digital inputs may be available if no analog inputs are needed.

Numbers and types of the onboard I/Os are listed in the table below:

Processor module	Power supply	No. and type of digital inputs	No. and type of digital outputs	No. and type of analog inputs	No. and type of analog outputs
PM56x-T(P), PM56x-T(P)-ETH	24 V DC	6 x 24 V DC *	6 x 24 V DC, 0.5 A max. (transistor)	2 x voltage *	1 x voltage or current
PM56x-R(P), PM56x-R(P)-ETH	24 V DC	6 x 24 V DC *	6 x relay output, 2 A max.	2 x voltage *	1 x voltage or current
PM56x-R(P)-AC, PM56x-R(P)-ETH-AC	100-240 V AC	6 x 24 V DC *	6 x relay output, 2 A max.	2 x voltage *	1 x voltage or current

* PM56x has 2 analog inputs which can be configured as digital inputs. If the analog inputs are configured as digital inputs, 8 digital inputs totally are available.

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 electrically isolated.

Note

The 2 analog inputs are not electrically isolated from the 24 V power supply of the processor module.
