The night nSP5 PCD series secondary relay and dimming pack is capable of switching and dimming incandescent lighting loads, certain line voltage dimmable fluorescent lighting loads, magnetic low voltage (MLV) lighting loads and electronic low voltage (ELV) lighting loads. Manual switching and adjustment of the dimming level is possible via WallPods or through the night SensorView software. The nSP5 PCD's two RJ-45 connectors make control wiring with standard CAT-5 cabling quick and easy. For mounting, the nSP5 PCD has an elongated chase nipple that allows it to be attached either directly through a 1/2 in knockout onto a junction box or to an adjacent box for meeting specific local code requirements in ceiling plenums.
