Where it sits in the control system
The 751-9301 is the device-level element in a WAGO Compact Controller 100 installation. It receives the field signals and control supply listed above and switches or conditions the load within the ratings shown in the Specifications table. Wiring and protective devices are sized against enclosure rating IP20, operating temperature -25 … +60 °C, mounting DIN-35 rail — not against a generic assumption.
Typical installations place it in control panels, machine builds and spare-part replacements, where the unit is matched to the original catalog number and the enclosure provides the mounting support listed above. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
