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 voltage bus P1 and 
P2 of the PM-E F pm DC24V PROFIsafe. 
SIL2/Category 3/PLd is attainable in both cases.
