The Power Load Controller is a versatile control device that can be used in a large number of applications. It provides on/off lighting, timed light switch, daylight harvesting, photo inhibit, occupancy based or vacancy based lighting control. The controller activates electrical loads with received input from a linked sensor or switch. The controller acts on transmissions of ambient light levels monitored by an wireless photo sensor. Occupancy/vacancy state monitored by a wireless occupancy sensor. Switch action from a wireless single or dual paddle wall switch, a wireless key card switch or a wireless door/window switch. Switch action from a gateway control implementing schedules or other events The controller can be used in distributed process applications to eliminate troublesome wiring runs using linked wireless electrical switches. A low voltage or line voltage event can be transmitted to the load controller triggering the dry-contact relay connected to any electrical load.
