LightSync Digital Photo Sensor Controller 4

Models: LSPSC4

The LightSync Digital Photo Sensor 4 controller incorporates a space-saving 4 head controller in 1 module. This LSPSC4 device accepts from 1 to 4 sensors each operated individually or averaged as one. The photocell controller monitors the light levels and transmits the data across the LightSync Digital data line to the lighting control panels. For daylight harvesting each sensor is mapped directly to the dimmer modules to adjust the dimming levels. Each sensor can also be mapped to control relays or relay groups with 8 individual set points for on/off control, sensor inputs incorporates a filter to eliminate false triggering from lightning or other sudden light changes. Compatible with the ILC Indoor and Outdoor sensors.
