Isolated relay module CRF-300

Fire-Lite’s CRF-300 Relay Module provides two isolated sets of Form-C dry-contact outputs for activating a variety of auxiliary devices, such as fans, dampers, door holders, control equipment, etc. CRF-300(A) provides two Form-C dry contacts that switch together. A trouble condition on the external power supply will never interfere with the rest of the system. Built-in type identification automatically identifies this device to the control panel.
