        Overview Manuals AC/Analog Loop Setup Relay & Network Product Applications

        Features:

        • Dual voltage domains: 120 V AC discrete inputs plus low-voltage analog channels
        • Embedded analog: four voltage inputs and two voltage outputs for qualified signals
        • Relay actuation: twelve contact outputs with grouped field supplies
        1766-L32AWAA fits MicroLogix 1400 systems that must combine AC discrete sensing with onboard voltage measurement and command signals.

        Its AC and analog circuits require different references, routing, shielding, and verification even though they share one controller enclosure.

        The exact AWAA suffix should remain tied to the terminal plan, analog scaling, relay grouping, communication configuration, expansion bank, and project archive.
        Apter Power can coordinate official-document checks, quotation, and sourcing support for 1766-L32AWAA.

        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.
        • AC inputs: route and protect the 120 V AC groups independently from low-voltage analog conductors.
        • Analog reference: verify COM ANA and field-device power before accepting raw channel values.
        • Shield grounding: terminate the drain at one end only and avoid parallel routing with AC load wiring.
        • Input injection: apply known voltages and compare raw twelve-bit counts before engineering-unit scaling.
        • Output loading: measure both voltage outputs at the field load and confirm the common-reference path.
        • Noise challenge: repeat analog tests while representative relay loads switch to expose coupling or grounding faults.
        • Relay groups: map common terminals, load voltage, suppression, and safe state for every output.
        • Ethernet messages: validate the selected supported protocol, peer role, data map, and timeout handling.
        • Local growth: preserve Bulletin 1762 module order and complete the bus-current check before expansion.
        • Mixed AC and analog equipment: combine 120 V AC status inputs with voltage process measurements.
        • Relay control panels: switch qualified contactor, valve, or indicator loads through grouped relay outputs.
        • Supervisory data exchange: share discrete and analog controller values through supported Ethernet or serial messaging.
        Description
        1766-L32AWAA combines twenty 120 V AC inputs and twelve relay outputs with four voltage inputs and two voltage outputs. This configuration supports AC discrete field circuits and embedded analog monitoring or commands within the MicroLogix 1400 communication and expansion architecture.

        The analog channels on 1766-L32AWAA use twelve-bit unsigned data and are non-isolated from internal logic, while the digital inputs belong to a separate AC voltage class. Shield grounding, cable separation, analog reference, AC common grouping, and relay suppression must therefore be planned as distinct wiring tasks.

        A replacement or new design using 1766-L32AWAA should validate the complete catalog suffix, AC input map, analog scaling, output groups, communication settings, expansion loading, and controller project. AWA omits the analog terminals, and DC-input variants require a different field-power design.

        Technical notes
        No 24 V DC user sensor source is assigned to 1766-L32AWAA. Provide separately protected field power for its analog transmitters and other low-voltage devices, reference those connected circuits to the documented analog common, and halt commissioning if an undocumented controller terminal is supplying external equipment directly.

        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
        Why can switching an AC relay load disturb an analog reading on 1766-L32AWAA?
        Inspect analog cable separation, one-end shield grounding, COM ANA reference, relay suppression, enclosure ground, and field-device power while trending raw counts during the switching event.
        How should an installer power a two-wire transmitter connected to 1766-L32AWAA?
        Provide a separately protected supply appropriate for the transmitter, follow the official analog wiring pattern, reference the signal to COM ANA, and do not assume the controller provides user 24 V DC.
        What should be checked when 1766-L32AWAA reports correct raw counts but the HMI value is wrong?
        Verify the HMI tag source, controller scaling endpoints, unsigned data interpretation, engineering-unit range, and message data type using known injected voltages.
        Can a DC-input MicroLogix 1400 project be moved to 1766-L32AWAA without rewiring?
        No. The digital inputs require 120 V AC field circuits; review voltage sources, device ratings, commons, protection, segregation, terminal mapping, and the project I/O definition before any migration.
        How can Ethernet communication on 1766-L32AWAA be accepted with a third-party Modbus TCP peer?
        Confirm client and server roles, register addresses, data types, byte order, polling, exception handling, and timeout behavior with a controlled map before connecting operational tags.
        Which pre-shipment evidence confirms that 1766-L32AWAA is not the non-analog AWA version?
        Obtain clear catalog and terminal-label photographs, verify IV and OV terminal presence, match the project analog map, and include series, condition, quantity, and destination in the purchase record.
