Photocell exterior low voltage 24VAC 10.8 to 161.5 lux

The EM is a low voltage photocell used for controlling exterior lighting. It works with Watt Stopper power packs and lighting control panels (Lighting Integrator and LP series panels) by signalling a change in light levels to the panel. One set of normally open, isolated relay contacts; contacts are closed when sensed light level is below dark setpoint, open when light level is above light setpoint. 8-second time delay and built-in setpoint deadband prevent cycling. 1/2... threaded male conduit base for easy mounting on conduit fittings or junction boxes.
