        More Information

        Overview Manuals AC Load Selection Scheduled Output Data Isolated Field Wiring Application
        • Provides sixteen individually isolated outputs for 74–265 V AC field circuits
        • Supports documented scheduled-output data referenced to controller system time
        • Requires a compatible 36-pin removable terminal block and AC load-duty review

        1756-OA16I is a ControlLogix isolated AC output module intended for independently wired 120 V or 240 V AC loads.

        Its channel isolation allows separate field connections, while scheduled-output operation depends on the selected module data format, controller ownership, and time synchronization.

        Confirm load current, inrush, inductive suppression, terminal-block selection, wiring, external protection, and scheduled-output configuration before commissioning.

        Availability, condition, price, and shipping time for 1756-OA16I are confirmed during quotation.

        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

        • Match every 1756-OA16I output to a 74–265 V AC, 47–63 Hz field load
        • Check steady-state current, inrush, minimum load, and inductive duty before connection
        • Apply external protection and suppression appropriate to the installed AC device
        • Select the documented scheduled-output data format only when the Logix application requires timed switching
        • Confirm controller ownership and Coordinated System Time synchronization before commissioning
        • Do not treat a scheduled command as confirmation that the external AC load actually changed state
        • Keep each isolated output and its field return consistent with the approved wiring drawing
        • Use the documented 36-pin removable terminal block and verify its keying and conductor torque
        • Inspect field power, fusing, grounding, and conductor identification before energizing
        • Individually isolated 120 V or 240 V AC solenoid and indicator circuits
        • AC contactor or starter interfaces whose steady-state and inrush duty fit the module limits
        • ControlLogix applications requiring scheduled switching of isolated AC outputs
        Description
        1756-OA16I is an Allen-Bradley ControlLogix 16-point individually isolated AC output module for 74–265 V AC, 47–63 Hz field circuits.

        Each output has an isolated field connection, and the module supports the documented scheduled-output data format for applications requiring controller-referenced output timing.

        Before installation, verify the Series A module, 36-pin removable terminal block, AC load and inrush duty, external protection, field wiring, scheduled-data configuration, and Coordinated System Time requirements.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Can 1756-OA16I switch DC field loads?
        No. 1756-OA16I is specified as an AC output module. Select an output module that directly matches the actual field-load voltage and switching duty.
        Can 1756-OA16I replace a non-isolated ControlLogix output module without rewiring review?
        No. Confirm each circuit's AC load, protective device, terminal assignment, and controller configuration before replacement.
        Why can one 1756-OA16I output fail while the module remains online?
        Check the individual field circuit, load, wiring, protection, terminal connection, and commanded state; module communication status does not prove an external AC circuit is healthy.
        Does 1756-OA16I include the removable terminal block required for field wiring?
        Treat the removable terminal block as a separately verified item unless the supplied stock description expressly includes it.
        What must be checked before moving 1756-OA16I into an existing ControlLogix slot?
        Verify slot assignment, electronic keying, output mapping, load wiring, fuse/protection arrangement, and the accepted controller project.
        Can 1756-OA16I be used where a circuit needs diagnostic output feedback?
        Confirm that the application needs only the documented isolated AC output function. Do not assume diagnostic feedback features from a different module family.
        Why should 1756-OA16I field circuits be checked before restoring automatic operation?
        Incorrect AC load wiring or an unreviewed output map can energize the wrong field device. Verify each controlled circuit in a safe, guarded condition.
