Product Description

The Allen-Bradley 1771-OW is a versatile output module in the 1771 I/O series, designed for use in PLC-5 and compatible Allen-Bradley systems. It features 8 individually isolated outputs, each capable of switching both AC and DC loads, making it highly flexible for industrial control applications. The module uses relay-based outputs, which allow it to handle a wide range of voltage levels and load types, including resistive, inductive, and lamp loads.

Product Specifications

Product Advantages

• Dual AC/DC Capability: Can switch both AC and DC loads, offering flexibility in mixed-voltage environments.
• Relay Isolation: Each output is isolated, reducing the risk of cross-talk and improving system reliability.
• Wide Voltage Range: Supports a broad spectrum of industrial voltages from 5V to 265V AC and 5V to 125V DC.
• LED Status Indicators: Each output has its own LED for quick diagnostics and troubleshooting.
• Form C Contacts: Allows switching of normally open or normally closed circuits depending on wiring.
• High Compatibility: Fully compatible with Allen-Bradley PLC-5 and 1771 I/O chassis systems.

Precautions

• Load Ratings: Do not exceed the maximum current ratings per output or per module to avoid relay damage.
• Inductive Loads: Use surge suppression (e.g., RC snubbers or diodes) when controlling inductive loads like motors or solenoids.
• Heat Dissipation: Ensure proper ventilation in the control cabinet, especially when operating near maximum current ratings.
• Wiring Practices: Use appropriately sized wires and ensure secure connections to prevent voltage drop or arcing.
• Environmental Protection: Since the module is open-style, it must be installed in a properly rated enclosure to protect against dust, moisture, and accidental contact.
• Power Off During Installation: Always power down the system before installing or removing the module to avoid damage or injury.

Product Applications

• Industrial Control Systems: Used to switch motors, solenoids, and actuators in manufacturing and process control.
• Alarm and Signal Systems: Activates horns, strobes, and indicator lamps in safety and notification systems.
• HVAC and Building Automation: Controls fans, dampers, and lighting in commercial and industrial environments.
• Packaging Machinery: Drives sealing bars, cutters, and other actuators in automated packaging lines.
• Material Handling: Manages diverters, stops, and conveyors in warehousing and distribution systems.
• Test Equipment and Rigs: Used in custom test benches where both AC and DC loads must be switched under program control.
