Allen-Bradley 1769-OW16 – CompactLogix Relay Output Module

Detailed Technical Overview of Allen-Bradley 1769-OW16 – CompactLogix Relay Output Module

The Allen-Bradley 1769-OW16 is a 16-point relay output module from the Compact I/O family, designed for use with CompactLogix and MicroLogix 1500 controller systems. Manufactured by Rockwell Automation, this module provides flexible and isolated relay outputs suitable for controlling both AC and DC loads, making it a versatile component in a wide range of industrial automation applications including machine control, process systems, and panel-based systems.

1769-OW16

✅ Key Features and Specifications

  • Output Type:Electromechanical relay contact outputs, allowing for wide voltage compatibility:

    • 5…265V AC

    • 5…125V DC

  • Number of Outputs:16 isolated relay outputs grouped into two banks of 8, with each bank having an independent common terminal, offering flexibility in wiring AC and DC devices in the same module.

  • Current Ratings:

    • 2.0 A per point (resistive load)

    • 8.0 A per module total (AC or DC)

  • Switching Ratings:

    • VA Rating (AC): Up to 276 VA at 120V AC, 690 VA at 240V AC

    • W Rating (DC): Up to 30 W at 30V DC, with appropriate derating for higher voltages

  • Contact Life:

    • Mechanical life: Over 10 million operations

    • Electrical life: Approx. 100,000 operations at rated load


⚡ Functionality and Performance

The 1769-OW16 is particularly suited for applications that require electrical isolation, high switching voltage, or a mix of AC/DC output devices. Relay contacts provide true dry contact switching, meaning no leakage current when the output is OFF—a benefit when driving low-power AC or DC devices.


Unlike solid-state output modules, relay modules can handle inductive and resistive loads without internal protection circuitry, offering enhanced compatibility with legacy or mixed-load systems. However, mechanical relays do have a slightly slower response time (typically <10 ms ON/OFF), making them better suited for standard-speed rather than high-speed switching.


🛠️ Installation and Wiring

  • Mounting:Compact DIN rail mounting, sharing the standard footprint of the Compact I/O series (dimensions: approx. 118 x 35 x 87 mm)

  • Backplane Current Draw:

    • 5V: 210 mA

    • 24V: 0 mA

  • Removable Terminal Block (RTB):Simplifies wiring and enables easy module replacement during maintenance without rewiring

  • Status Indicators:One LED per output channel, providing real-time indication of output status for quick diagnostics


🌐 Environmental Ratings and Compliance

  • Operating Temperature: 0°C to 60°C (32°F to 140°F)

  • Storage Temperature: -40°C to 85°C

  • Shock and Vibration Resistance: Designed for industrial environments

  • Certifications:

    • UL, c-UL, CE

    • CSA, Class I Div 2 (Hazardous Locations)


🏭 Typical Applications

The 1769-OW16 is highly effective in systems that require:

  • Switching of AC contactors or relays

  • Control of DC-powered devices like lamps, indicators, or solenoids

  • Field isolation between load groups

  • Mixed-load control within the same module (AC & DC)

  • Systems with frequent maintenance, thanks to the removable terminal block and replaceable relay contacts


✅ Conclusion

The Allen-Bradley 1769-OW16 relay output module provides flexibility, electrical isolation, and mixed-load handling, making it a strong choice for automation professionals working with CompactLogix or MicroLogix systems. Its combination of wide voltage compatibility, isolated outputs, and rugged relay technology ensures reliable performance across a variety of industrial environments. Whether for panel builders, OEMs, or system integrators, the 1769-OW16 is a robust and adaptable output solution.
