Hochiki CHQ-MRC2(HFP)-SCI Analog Addressable Main Relay Module with Short Circuit Isolator

The CHQ-MRC2 main relay module provides a single relay output for controlling mains-voltage equipment. It is used in damper and exhaust fan control and equipment shutdown scenarios. It also carries an input that can be used for power failure monitoring or other purposes. The built-in short circuit isolator prevents a fault at the module location from bringing down the rest of the loop.
