Description
The RLY-4 is designed to communicate with the FCS Multi Channel System Controllers via Modbus® communications protocol. It offers 4 physical relays rated 5 amps @ 240 VAC and 2 horn/strobe drives rated 0.5 amp @ 24 VDC. Similarly, the RLY-4 offers 8 physical relays and 4 horn/strobe drives.
The RLY-4 and RLY-8 can be used to control remote alarms, strobes, exhaust fan starters, make up air fan contactors, etc. In the event that the connection is lost between the controller and the remote relay, a user configurable default state can be set to ensure the relays continue to operate as required. Both devices come in a standard water / dust tight, corrosion resistant ABS / polycarbonate enclosure with a hinged, secured door.
