Features:
- Eight-channel AC output module for a 1771 I/O chassis.
- One status indicator corresponds to each output channel.
- A separate fuse-blown indicator reports an open output fuse.
1771-OM is an Allen-Bradley 1771-series AC output card for installed PLC-5 I/O systems.
Rockwell product data distinguishes 1771-OM from other 1771 output models and identifies eight outputs and a fuse-blown indication.
Output load selection and field wiring require the exact revision data and a qualified electrical review; this overview is not a circuit design or compatibility approval.
Apter Power supports exact-model documentation review and sourcing for the Allen-Bradley 1771-OM AC output module.

- Exact-model spare for an installed 1771 chassis using an AC output card.
- Maintenance of legacy PLC-5 output channels where 1771-OM is recorded.
- Part identification during a 1771 I/O migration or controls retrofit.
- Confirm 1771-OM on the removed module label; 1771-OA, OMD and OQ16 are separate products.
- Check the installed 1771 chassis and original field wiring arm identification.
- Have an electrical specialist compare the actual load and circuit with the exact Rockwell product data before selection.
- Compare the eight output indicators and the fuse-blown indicator with the controller command and fault record.
- An illuminated output indicator does not by itself confirm that the external load is energized.
- Investigate the field circuit and module only through the site-approved electrical diagnostic procedure.
- Record each original 1771-OM output assignment and terminal connection under the site change procedure.
- Use revision-specific wiring and safety documentation; the model name alone does not establish a load match.
- Follow qualified isolation, testing and return-to-service practices for the installed circuit.
