PM554-TP and PM554-RP replacement
For an existing AC500 system, can we replace the PM554-TP with the PM554-RP ? Is that technically proposed or not ?
Many thanks in advance.
Technically that is possible, but not directly 1:1.
For the hardware part, you should take in consideration, that TP is with transistor outputs, when RP model is with relay outputs, in two groups, each group with 3 contacts and common. You have to re-arrange the connection of the output circuit. See below the connection diagram for both from AB help
For the application, you don't have to do modifications.
