Model CHQ-DRC2/M(SCI) is a Marine Approved Dual Relay Controller
module designed to provide two general-purpose relay outputs, each
output can be driven separately for control of such devices as dampers or
for control of plant and equipment shutdown. The monitored input can beused for local power supply fault monitoring or as a general-purpose input.The unit also features an integral short-circuit isolator. The CHQ-DRC2/M(SCI)utilises simple DIL switches forreliable addressing. A backbox is also available(CHQ-BACKBOX) which, when used in conjunction with the CHQ-DRC2/M(SCI),increases the IP rating to IP65.
