Product Advantages and Features

1. High-Current Switching
   Each relay can handle up to 2A, making it suitable for directly driving medium-sized loads without additional intermediate relays.
2. Electrical Isolation
   2,500VAC isolation protects the PLC from electrical noise and voltage spikes, enhancing system reliability.
3. Universal Compatibility
   Works with both AC and DC loads, providing flexibility for diverse industrial applications.
4. Visual Status Monitoring
   Channel-specific LEDs allow quick visual verification of output states, simplifying troubleshooting.
5. Robust Design
   Industrial-grade components and surge protection ensure long-term performance in harsh environments.

Application Areas

1. Industrial Machinery
   Controls motors, solenoids, and actuators in packaging machines, conveyors, and assembly lines.
2. HVAC Systems
   Switches heating/cooling equipment, dampers, and fans in building automation.
3. Material Handling
   Operates relays for crane controls, lift gates, and automated storage systems.
4. Lighting Control
   Manages industrial lighting circuits based on occupancy or time schedules.
5. Power Distribution
   Controls contactors for powering industrial equipment or machinery.

Precautions

1. Load Matching
   • Ensure the load current and voltage do not exceed the relay’s rated capacity (2A/250VAC or 2A/30VDC).
   • For inductive loads (e.g., solenoids, motors), consider derating the relay capacity by 50% to account for inrush currents.
2. Wiring
   • Use appropriately sized wire (≥0.75mm²) to handle the rated current.
   • Separate power and signal wiring to minimize electromagnetic interference.
3. Heat Dissipation
   • Avoid installing the module in enclosed spaces without adequate ventilation, especially when driving high-current loads.
4. Maintenance
   • Periodically inspect relay contacts for signs of wear or arcing, especially in high-cycle applications.
   • Replace the module if contacts become pitted or fail to switch reliably.
5. Environmental Considerations
   • Do not install in areas exposed to moisture, dust, or corrosive substances.
   • For applications with frequent load cycling, consider using solid-state relays instead for longer life.
