The CHQ-DRC2(SCI) is a Dual Relay Controller providing 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 monitoring or as a general-purpose input.
A DIN rail-mountable version is also available, with both models featuring an integral short-circuit isolator (SCI). The CHQ-DRC2(SCI) uses simple DIL switches for reliable loop addressing. An optional back box (CHQ-BACKBOX) can be fitted to raise the IP rating to IP65.
