Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
Where it sits in the control system
The 751111 is the device-level element in a Pilz industrial component installation. It receives the field signals and control supply listed above — DC — and switches or conditions the load within the the rated ratings shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in control panels, machine builds, spare-part replacements, where the unit is matched to the original catalog number and the enclosure provides DIN rail / panel support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Selection notes for Pilz 751111
