The SP20-RD4 is the latest addition to the Greengate Switchpacks family, delivering a wide array of switching solutions in a single unit. This robust switchpack is designed to deliver unmatched performance. The SP20-RD4 features robust and reliable mechanical latching relays, exclusive fail-safe circuitry, daylight harvesting, bi-level switching and is configurable for energy code requirements. The switchpack is specifically designed to handle high inrush electronic ballast loads and offer unmatched durability and service.
Switchpacks provide 24 VDC operating voltage to all low voltage, 24 VDC occupancy sensors and daylighting controllers. 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.
