Allen-Bradley 1769-OA16 CompactLogix 16-Point AC Output Module

Product Overview

The Allen-Bradley 1769-OA16 serves as a high-density digital output solution for the CompactLogix platform. This module provides 16 solid-state AC outputs, enabling the controller to switch power to solenoids, contactors, and motor starters safely. We supply this unit as 100% Brand New and Original, ensuring your control system utilizes factory-certified hardware capable of handling diverse AC voltage requirements across global industrial standards.

Technical Specifications

Engineering Advantages

• Mixed-Voltage Versatility: The 1769-OA16 supports the simultaneous mixing of 120V and 240V AC sources within a single module. This hardware flexibility allows engineers to control different circuit voltages on the same rack, reducing the total module count and saving significant panel space.

• Solid-State Switching Precision: The module utilizes Triac-based solid-state switching. This technology eliminates the mechanical wear associated with traditional relay contacts, providing an almost infinite operational lifespan for high-frequency switching applications.

• Enhanced Electrical Isolation: Two isolated groups of eight outputs protect the internal backplane and the CPU from field-side electrical surges. This isolation also prevents cross-talk between different power sources, ensuring stable performance in electrically noisy environments.

• Rapid Response Timing: The module achieves a maximum signal delay of just 1/2 cycle for both turn-on and turn-off operations. This speed ensures precise coordination for time-sensitive tasks, such as high-speed sorting or synchronized valve actuation.

• Efficient Thermal Management: Optimized internal circuitry limits total heat dissipation to just 4.9 Watts. This low thermal footprint prevents localized hotspots within the CompactLogix rack, even when the module operates at its full 60 °C temperature rating.

FAQs

• Can I mix AC and DC voltages on this module?

  No. The 1769-OA16 exclusively handles AC voltages within the 85 to 265V range. For DC applications, you must utilize a DC-specific output module like the 1769-OB16 to prevent catastrophic hardware failure.

• What is the minimum current requirement for the outputs?

  The module requires a minimum on-state current of 10 mA. If your connected load (such as a small pilot light or high-impedance relay) draws less than 10 mA, the output may not switch off correctly. In these cases, you should install a "bleeder" resistor in parallel with the load.

• Does this module require a specific terminal block?

  Yes. Like all 1769 modules, you must use a Removable Terminal Block (RTB) for field wiring. Ensure you secure the finger-safe cover after wiring to maintain the module's safety rating.

• Is there a limit to how many 1769-OA16 modules I can add to a rack?

  The total number of modules depends on your specific CompactLogix controller's expansion limit and the Power Supply Distance Rating. The 1769-OA16 has a distance rating of 8, meaning it must stay within 8 slots of the system power supply.
