Description
The RLY-4 and RLY-8 are remote relay devices that offer up to four and eight (respectively) additional SPDT dry contact relays to a fixed gas detection system. The RLY-4 is specifically designed to communicate with both the QCC Quad Channel Controller and the FCS Flexible Control System via Modbus® communications protocol. The RLY-8 is designed to work with the FCS and FCS-8 only. 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.
The relays are rated 5 amps @ 240 VAC each and can be used to control remote alarms, strobes, exhaust fan starters, make up air fan contactors, etc. Both devices come in a standard water / dust tight, corrosion resistant ABS / polycarbonate enclosure with a hinged, secured door.
Specifications
Product Codes
