Where it sits in the control system
The 774318 is the device-level element in a Pilz industrial component installation. It receives the field signals and control supply listed above — AC — 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 774318
Pilz 774318 — Industrial automation component supplied as a like-for-like replacement, selected by catalog number and published ratings. The figures below are taken from the specification table on this page for catalog number 774318; confirm the installed unit's part number and revision so the replacement matches both electrically and mechanically.
- Enclosure rating: IP20 (IEC 60529) — Check this value against the nameplate of the installed unit before ordering.
- Rated insulation voltage Ui: 690 V (IEC 60947-4-1) — Match it to the existing panel and upstream protection.
- Mounting: DIN rail / panel — Record it with the other nameplate data when sourcing a replacement.
- Rated impulse withstand Uimp: 6 kV (IEC 60947-4-1) — Confirm the revision of the installed unit before a like-for-like replacement.
Cross-check the ratings above with the installed device before confirming the order.
