Information About XP2-SM-4S-20
The XP2-SM-4S-20 is part of the Lutron SoftSwitch XP2 series, engineered to handle heavy-duty switching applications while maintaining longevity and reliability. Using patented SoftSwitch® technology, the module eliminates relay arcing by pre-charging contacts before closing, ensuring silent, durable, and flicker-free operation. It features four independent relay circuits, each capable of managing up to 20 amps of load depending on type, making it ideal for fluorescent, LED, or HID lighting control. Designed for integration with Lutron’s lighting management systems, the XP2-SM-4S-20 supports centralized relay control, energy management, and flexible configuration for multi-zone applications.
Key Features:
- Four Independent Circuits: Controls up to four lighting loads with separate relay channels.
- High Load Capacity: Rated for 16A or 20A per circuit depending on load type.
- SoftSwitch® Technology: Eliminates relay arcing for extended relay life and silent operation.
- Versatile Voltage Support: Operates on 120/277 VAC, suitable for commercial and industrial systems.
- Low Maintenance: Solid-state control reduces mechanical wear common to traditional relays.
- Flexible Integration: Designed for use in centralized or distributed Lutron lighting control panels.
- Energy Efficiency: Provides reliable control for energy-saving lighting schedules and occupancy-based systems.
- Durable Construction: Built for continuous-duty commercial applications.
The XP2-SM-4S-20 delivers the reliability and precision required for high-performance lighting control in demanding commercial and architectural environments.
