Intended Purpose

Processor Module PM55x

Processor Module PM55x provides 8 onboard digital inputs (24 V DC) and 6 onboard digital outputs (depending on variant 24 V DC transistor outputs or relay outputs).

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
PM55x-T(P), PM55x-T(P)-ETH	24 V DC	8 x 24 V DC	6 x 24 V DC, 0.5 A max. (transistor)	none	none
PM55x-R(P)	24 V DC	8 x 24 V DC	6 x relay output, 2 A max.	none	none
PM55x-R(P)-AC	120 to 240 V AC	8 x 24 V DC	6 x relay output, 2 A max.	none	none

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.
