NOTICE!
Risk of malfunctions in the plant!
The outputs may switch on for a period of 10 to 50
µ
s if the process supply
voltage UP/ZP is switched on.
This must be considered in the planning of the application.
CAUTION!
Risk of damaging the processor module!
The outputs are not protected against short circuit and overload.
–
Never short-circuit or overload the outputs.
–
Never connect the outputs to other voltages.
–
Use an external 3 A fast protection fuse for the outputs.
Connection of the Digital Relay Outputs (PM55x-R(P) only)
The following figures show the electrical connection of the digital relay outputs to the processor
modules:
Connection of digital relay outputs (24 VDC)
Connection of digital relay outputs (100-240
VAC)
WARNING!
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!
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.
