Connection of \ the Digital Relay Outputs (PM56x-R(P) only)ΒΆ

The following figures show the electrical connection of the digital relay outputs to the processor modules:

Connection of digital relay outputs (24 V DC) Connection of digital relay outputs (100-240 V AC)

Warning

:strong:Risk of death by electric shock!

The terminals of the module can carry 240 V voltage.

Make sure that all voltage sources (supply and process voltage) are switched off before you begin with operations at the system.

Warning

:strong:For screw terminals only: Danger of death by electric shock!

The IP 20 protection degree is only provided if all terminal screws are tightened.

Tighten all screws of unused load terminals of relay outputs if voltages > 24 V are connected to the relay group.

Caution

:strong:Risk of damaging the processor module!

  • Never short-circuit or overload the outputs.
  • Never connect inductive loads without an external suppression against voltage peaks due to inductive kickback.
  • Never connect voltages > 240 V. All outputs must be fed from the same phase.
  • Use an external 5 A fast protection fuse for the outputs.
