Where it sits in the control system
The 2963941 is the device-level element in a Phoenix Contact industrial component installation. It receives the field signals and control supply listed above — 24 V DC -15 % / +10 % — 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 35 mm DIN rail (IEC 60715) support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Selection notes for Phoenix Contact 2963941
Phoenix Contact 2963941 — 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 2963941; always cross-check the catalog number and hardware revision on the nameplate before placing an order.
- Operating temperature: -25...+60 °C (IEC 60068-2-1) — Confirm the revision of the installed unit before a like-for-like replacement.
- Terminal wire size: 50 Ω — Use it as the reference when cross-checking a current-production equivalent.
- Safety integrity SIL/PL: 3 — Verify it in the project documentation before confirming the order.
- Enclosure rating: IP20 (IEC 60529) — Check this value against the nameplate of the installed unit before ordering.
For a discontinued unit, match function and electrical ratings rather than the label alone.
