Overview

The NSI Industries 2129A is a heavy-duty, fixed-position conduit mount photocontrol designed for reliable outdoor lighting automation. This unit features a durable cast zinc housing and a 1/2" threaded stem for conduit mounting. It operates across a wide voltage range of 120-277VAC and offers adjustable light level control, turning ON between 1 to 5 footcandles (fc) and turning OFF between 3 to 15 fc. The 2129A includes a 190-joule MOV for surge protection and a conformal coated cadmium sulphide photocell that resists moisture and contaminants, ensuring longevity. It provides a time delay for both ON and OFF switching to prevent false triggers from transient light sources like headlights or lightning. The photocontrol fails in the ON position for safety. Applications include parking lots, building perimeter lighting, and outdoor signage. SKU: 2129A. Meets ANSI/UL773A standards. Operates from -40 °F to +140 °F (-40 °C to +60 °C). Power consumption averages under 1 watt. Features a 5-year warranty.
