Which installed system position is intended for 1746-OW16?

Install 1746-OW16 only in the documented Allen-Bradley SLC 500 I/O position and compare the complete catalog marking with the approved hardware list.

What field signals or controlled function does 1746-OW16 handle?

Its documented role is sixteen grouped relay output commands; preserve the assigned channel, network or controller function during service.

Which companion hardware must be matched to 1746-OW16?

Match 1746-OW16 with SLC 500 chassis and SLC processor and backplane, including the documented rack, cable and project identity.

Which electrical rating must be checked before wiring 1746-OW16?

Verify output type: Normally open relay. Do not transfer limits from another catalog number.

What configuration should be recorded before replacing 1746-OW16?

Record the as-found position, conductors, addressing, firmware and software revision, then restore only the approved Allen-Bradley SLC 500 I/O configuration.

Which isolation and handling controls apply to 1746-OW16?

Isolate all documented supply and field energy, use ESD controls and protect keyed connectors before handling 1746-OW16.

How should an engineer commission 1746-OW16?

Power up in a controlled sequence, review device and host diagnostics, then prove the intended contactor and relay command bank function.

Can 1746-OW16 replace a visually similar module without an engineering review?

No automatic substitution is assumed; compare the complete catalog number, interfaces, ratings and approved system revision.

Information

Overview Manuals Common Applications Product Precautions

Allen-Bradley 1746-OW16 is slc 500 sixteen-point relay output module. It switches sixteen relay output circuits from an SLC 500 controller for AC or DC field loads.

Provides sixteen normally open relay outputs
Accepts AC or DC field circuits
Divides outputs into two isolated groups
Occupies one SLC 500 I/O slot

1746-OW16 operates with SLC 500 chassis, SLC processor and backplane, removable terminal block, AC or DC field loads.

Engineered applications include Contactor and relay command bank, Mixed-voltage actuator control, Machine permissive outputs, SLC output-module replacement.

Important Notice: Record the slot, terminal block, group commons, load voltage and output addresses; isolate every field source before removing the module.

The first document presents model-specific engineering data. The second provides a separate installation, connection, commissioning and acceptance workflow.

Contactor and relay command bank

Switches contactors and interposing relays from SLC logic.

Mixed-voltage actuator control

Interfaces documented AC and DC loads through isolated relay groups.

Machine permissive outputs

Drives machine permissive and alarm circuits.

SLC output-module replacement

Renews the exact output position while preserving addressing.

Read the applicable Allen-Bradley instructions before work. Verify 1746-OW16 and the installed Allen-Bradley SLC 500 I/O configuration.

Verify the complete 1746-OW16 marking and its assigned Allen-Bradley SLC 500 I/O position before work.

Place the connected contactor and relay command bank process in the approved maintenance state.

Isolate applicable power and sixteen grouped relay output commands field energy before disconnecting conductors.

Record connector, conductor, address, firmware and software identities before removal.

Use ESD controls and protect keyed interfaces, exposed contacts and electronic assemblies.

Confirm the installed SLC 500 chassis and SLC processor and backplane against the approved project.

Restore power in a controlled sequence and review device, network and host diagnostics.

Prove the intended mixed-voltage actuator control function and retain the final test result.
