LEVITON O4C20-MDW Provolt Vacancy Sensor Multi-Technology, Line Voltage, Dual Relay 120 - 277 VAC, White

The Leviton Provolt™ Series of occupancy sensors features self-contained line-voltage occupancy sensors and photocells in one unit. The integrated design alleviates the need for separate power pack, occupancy sensor and photocell wiring, making it a low-cost and efficient energy management solution for new construction and retrofits. For true daylight harvesting applications, integrated photocells provide consistent Daylight Design Levels by actively switching the connected load(s) ON and OFF in response to available natural light to maximize energy savings. Output short circuit protection - protection against low voltage wiring errors. Industry-exclusive self-configuring local manual switch input supports momentary and maintained switches - no special control stations required. Zero-crossing circuitry for extended life of the relay. Easy installation into junction boxes with Leviton exclusive screw guides, coasters and terminal blocks. Passed rigorous NEMA 410 testing for electronic ballast rating.
