Incoming 24 VDC supply to Electronic Modules with Technology Functions
Depending on whether the electronic and load current supplies are electrically isolated in the
electronic modules with technology functions (positioning, counting), you must comply with
the following wiring rules:
● If electrically isolated, you can connect the electronic module to an external 24 VDC
power supply.
● if not electrically isolated, you must supply the electronic module from the voltage bus P2
of the PM-E F pp DC24V PROFIsafe.
SIL2/Category 3/PLd is attainable in both cases.
