EM-24A2 – AC LOW VOLTAGE PHOTOCELL
This is the AC low voltage photocell. Typically mounted so the light level window faces the northern sky, the EM photocell provides an ON signal when the ambient light level drops below a preset “dark” setpoint. It then provides a signal OFF as the ambient light level rises above the preset “light” setpoint. The setpoint can be changed for specific applications by opening and closing the photocell’s aperture window. Normally, a lighting control panel or a power pack supplies power to the photocell. The photocell’s relay contact red wires are connected to the panel or to a low voltage controlled load. Check out Wattstopper DLM products here.
- 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.
