*Updated 2021* Dual Relay Switchpacks provide 24 VDC operating voltage to all low voltage, 24 VDC, Greengate occupancy sensors and day lighting controllers. These switchpacks can be used where two circuits need to be controlled at the same point. A single switchpack can provide power for up to five sensors. Up to ten switchpacks can be connected to one sensor for control of multiple circuits. Isolated contacts may also be used to control HVAC, contactors, motors, etc.Replaces separate transformers and relaysZero-crossing circuit provides increased durability, especially with today’s high inrush loadsCapable of switching up to 20 ampsSuitable for Plenum installationsRated for Ballast, Tungsten and Motor Loads
