        Features:

        • High-Density 16-Point Sourcing Signal Switching for 24V DC Industrial Field Devices
        • Solid-State Output Architecture with Integrated Optical Isolation and Low Thermal Dissipation
        • Full Interoperability with CompactLogix Controllers and MicroLogix 1500 Expansion Systems
        The Allen-Bradley 1769-OB16 Solid State 24V DC Source Output Module functions as a high-density digital expansion output component within a Compact I/O system, delivering precise switching signals to field equipment. It processes controller logic instructions and continuously controls up to 16 independent sourcing outputs operating within an ON-state voltage range of 20.4 VDC to 26.4 VDC, delivering up to 0.5 A per channel. Solid-state switching technology provides rapid, contact-free operation that eliminates mechanical contact wear, arcing, and acoustic noise while optocouplers isolate internal backplane logic from external field noise and transient voltage spikes.

        The 1769-OB16 provides essential discrete output capabilities across localized or distributed control networks, directly driving field loads such as solenoid valves, indicator lights, relay coils, and low-power actuators. Installed directly alongside a controller or in an expansion bank, the module mounts securely on a standard 35 mm DIN rail or via dedicated upper and lower panel mounting tabs. Adjacent modules in the bank lock together physically using top and bottom tongue-and-groove slots, while electrical connectivity across the Compact I/O backplane is established through a sliding bus lever that engages female bus pins with the neighboring stationary male connector.

        In standard field applications, the 1769-OB16 operates in a sourcing configuration where each channel sources current from the positive side of the DC power supply to a ground-referenced load. Individual channel operational states and module diagnostics are continuously reflected by the front-panel status LEDs, allowing technicians to verify I/O activity and diagnose open-wire or unpowered field conditions quickly. Wiring connections are consolidated on a Removable Terminal Block (RTB) with a finger-safe cover, fastened by top and bottom retaining screws to permit fast module replacement without disconnecting individual field wires.

        The 1769-OB16 Allen Bradley  Solid State 24V dc Source Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        • Driving DC Actuators & Solenoids: Controlling hydraulic or pneumatic directional control valves on manufacturing lines.
        • Operating Status Indicators: Illuminating control panel pilot lights, stacked beacon tower lights, and audible alarms.
        • Interfacing with Auxiliary Relays: Energizing coils on larger interposing relays or motor starters when the required current exceeds the module’s threshold.
        • High-Speed Discrete Switching: Leveraging ultra-fast solid-state transition times (0.1 ms turn-on, 1.0 ms turn-off delay) for precise, repetitive timing tasks where mechanical relays would wear out prematurely.
        • Local Controller I/O: Directly installs next to CompactLogix L3x, CompactLogix 5370, or older MicroLogix 1500 controller banks.
        • Distributed/Remote I/O: Operates in remote chassis assemblies utilizing communication adapters such as the 1769-AENTR (EtherNet/IP) or 1769-ADN (DeviceNet).
        • Bus Current Budgeting: It draws 200 mA at 5.1V DC from the backplane. System designers must calculate the cumulative current consumption to ensure the power supply is not overloaded.
        • Bus Termination: A 1769-ECR (right) or 1769-ECL (left) bus end cap terminator is mandatory on the final module of any bank to prevent communication faults.
        • Controller Firmware Dependence: System logic behaviors and communication protocols are dictated by the firmware of the controlling master device (e.g., the CompactLogix CPU or network adapter).
        • Electronic Keying: Within programming environments like RSLogix 5000 or Studio 5000 Logix Designer, compatibility is maintained via Electronic Keying properties. When configuring the module profile, you can select Exact Match, Compatible Module, or Disable Keying to dictate how strictly the controller checks the vendor, product type, and major/minor hardware series before permitting communication.
        • Hardware Revisions: If firmware/software compatibility problems emerge during system upgrades, they are solved either by updating the parent controller's firmware via ControlFlash or replacing the physical 1769-OB16 unit with a newer hardware series (such as Series B) that complies with modern controller handshakes.
        Description
        The Allen-Bradley 1769-OB16 Solid State 24V DC Source Output Module is a high-density, 16-channel digital output expansion component belonging to the Compact I/O module family. This 1769-OB16 module is designed to provide 24V DC sourcing output signals, delivering reliable switching power directly to field loads in industrial control systems. Operating with a source output configuration, the 1769-OB16 supplies current from the positive side of the DC power supply to connected devices such as solenoid valves, indicator lights, relay coils, and small motor starters. Built-in optical isolation protects the backplane electronics and controller logic from electrical noise, voltage spikes, and ground loops common in industrial environments.

        This 1769-OB16 module is specifically designed to solve the challenges of high-density DC load control, panel space constraints, and electrical noise interference in automated control systems. By offering 16 solid-state outputs within a compact footprint, the 1769-OB16 solves the problem of high wiring complexity and bulky cabinet layouts, allowing engineers to handle numerous field devices efficiently without requiring larger enclosures. Furthermore, because solid-state switching replaces mechanical contacts, the 1769-OB16 eliminates wear and tear, contact arcing, and acoustic noise, dramatically improving system reliability and reducing downtime caused by relay failure in high-cycle applications.

        The 1769-OB16 is widely applied across various automated industries, including material handling, automotive assembly, packaging systems, food and beverage processing, and water/wastewater treatment. In these operational settings, the 1769-OB16 is ideal for driving pneumatic valves, actuators, alarm towers, pilot lights, and interlock relays. It seamlessly integrates with Allen-Bradley CompactLogix controllers or acts as distributed I/O controlled by MicroLogix 1500 systems, making the 1769-OB16 a versatile standard across localized automated production lines and centralized machinery networks.
