Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
Where it sits in the control system
The 1794-IJ2 is the device-level element in an Allen-Bradley I/O module installation. It receives the field signals and control supply listed above — 24 V DC (IEC 61131-2) — 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 packaging machines, conveyor transfer cells, small process skids, 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 Allen-Bradley 1794-IJ2
Allen-Bradley 1794-IJ2 — 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 1794-IJ2; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
- Certifications: CE, UL, cULus — Record it with the other nameplate data when sourcing a replacement.
- Supply voltage: 24 V DC (IEC 61131-2) — Confirm the revision of the installed unit before a like-for-like replacement.
- Operating temperature: 0...+55 °C (IEC 60068-2-1) — Use it as the reference when cross-checking a current-production equivalent.
- Mounting: 35 mm DIN rail (IEC 60715) — Verify it in the project documentation before confirming the order.
For a discontinued unit, match function and electrical ratings rather than the label alone.
