Product Description

The Allen-Bradley 1771-OA1 is an 8-point AC output module designed for use in PLC-5 and SLC 500 programmable controller systems. This module provides 8 individually fused outputs capable of switching AC loads such as contactors, relays, indicators, and motor starters. Each output is optically isolated, ensuring reliable operation and protection from electrical noise and voltage spikes.

Product Specifications

Product Advantages

• Individual Fusing: Each output point is separately fused, enhancing safety and minimizing downtime due to overloads.
• Wide Voltage Range: Supports a broad AC voltage range (85–265V AC), making it suitable for global industrial applications.
• Optical Isolation: Protects the PLC backplane from electrical noise and high-voltage transients.
• Status Indication: Each output has its own LED, enabling quick visual diagnostics.
• Proven Reliability: Built to withstand harsh industrial environments with robust construction and temperature tolerance.
• Ease of Maintenance: Hot-swappable in supported systems and modular design simplifies replacement and upgrades.

Precautions

• Load Compatibility: Ensure connected loads are within the 2A per point and 8A per module ratings to avoid fuse blowing or damage.
• External Fusing: Although the module includes individual fuses, additional external protection may be required for high-inductive or capacitive loads.
• Heat Dissipation: Ensure proper ventilation in the control cabinet, especially when operating near maximum current and temperature limits.
• Wiring Practice: Use appropriate wire gauges and follow proper grounding practices to reduce noise and voltage spikes.
• Module Handling: Power down the system before installing or removing the module to prevent electrical shock or damage.
• Environment: Avoid exposure to corrosive gases, dust, or excessive moisture unless properly protected.

Product Applications

• Motor Control: Used to switch AC motor starters, contactors, and solenoids in manufacturing and process control.
• Indicator and Alarm Systems: Controls lamps, horns, and visual indicators in control panels and HMI systems.
• Industrial Automation: Integrated into machinery for actuating valves, heaters, and other AC-driven devices.
• Material Handling: Drives conveyors, diverters, and other material transport systems.
• HVAC Systems: Manages AC-driven actuators and fans in building automation.
• Packaging Machinery: Controls sealing arms, labelers, and other AC-powered packaging equipment.
