The CHQ-DRC2(SCI) is a Dual Relay Controller that provides two general-purpose relay outputs, each independently controllable for managing devices such as dampers or plant and equipment shutdown. Its monitored input can be used for local power supply fault detection or as a general-purpose input.
A DIN rail-mountable version is also available, with both models incorporating an integral short-circuit isolator (SCI). The CHQ-DRC2(SCI) features simple DIL switches for reliable addressing. An optional back box (CHQ-BACKBOX) can be used to increase the IP rating to IP65.
