Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
Where it sits in the control system
The 2901873 is the device-level element in a Phoenix Contact industrial component installation. It receives the field signals and control supply listed above — the rated supply — 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 Phoenix Contact 2901873
Phoenix Contact 2901873 — 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 2901873; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
- Terminal wire size: 0.14 mm² ... 1.5 mm² — Confirm the revision of the installed unit before a like-for-like replacement.
- Weight: 19.9 g — Use it as the reference when cross-checking a current-production equivalent.
- Input voltage range: 12 V DC ... 24 V DC — 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.
