Product Description
The Allen-Bradley AC Output Module is a solid-state or relay-based output module designed for use in PLC-5, SLC 500, and other compatible Allen-Bradley programmable controller systems. This module enables PLCs to control AC-powered devices such as motors, solenoids, lamps, contactors, and alarms. Each output point is typically optically isolated to protect the PLC from electrical noise and voltage spikes. These modules are widely used in industrial environments where reliable AC switching is required.

Product Advantages
- High Compatibility: Designed to integrate seamlessly with Allen-Bradley PLC-5 and SLC 500 systems.
- Optical Isolation: Protects the PLC backplane from high-voltage transients and electrical noise.
- Status Indication: Each output includes an LED for quick diagnostics and troubleshooting.
- Modular Design: Hot-swappable in some systems, reducing downtime during maintenance.
- Flexible Load Control: Supports a wide range of AC loads including inductive and resistive types.
- Fused Protection: Many models include individual point fusing to enhance safety and reliability.
Precautions
- Check Load Ratings: Ensure connected loads do not exceed the module’s current and voltage ratings.
- Use External Fusing: If not internally fused, use appropriate external fuses to protect each output.
- Avoid Mixed Voltages: Do not mix different AC voltages on the same module unless specifically allowed.
- Heat Dissipation: Ensure proper ventilation in the control cabinet, especially when driving high-current loads.
- Wiring Safety: Turn off power before installing or servicing the module to prevent electric shock.
- Surge Protection: Use surge suppressors when controlling inductive loads like motors or solenoids.
Product Applications
- Motor Control: Used to switch AC motors, fans, and pumps in manufacturing and process control.
- Indicator and Alarm Systems: Drives AC lamps, buzzers, and horns in control panels and HMIs.
- Heater Control: Manages AC-powered heaters in ovens, dryers, and thermal systems.
- Conveyor Systems: Controls motors, diverters, and stoppers in material handling lines.
- Packaging Equipment: Activates sealing bars, labelers, and other AC-driven actuators.
- Building Automation: Applied in HVAC systems to control dampers, fans, and lighting.
