CHQ-DRC2(SCI) is a relay controller module designed to provide 2 general purpose relay outputs, each of which can be controlled separately to manage devices such as gates or to control the shutdown of plant and equipment.

The supervised input can be used for fault monitoring or as a general purpose input.

Available in DIN-mounted version, both models have integrated short-circuit isolator.

A subsequent box (CHQ-BACKBOX) is also available which, when used in conjunction with the CHQ-DRC2(SCI), increases the IP rating to IP65.
