Remote Relays for QCC & FCS (RLY-4 / RLY-8)

    Key Features

  • » 
    Increases the number of available relays
  • » 
    User selectable gas alarm activation level for each relay (set at the controller)
  • » 
    User selectable “Failsafe” and latching operation (set at the controller) » ON/OFF Delay configurations (set at the controller)
  • » 
    User configurable to revert to a default state if connection is lost with the controller (set at the controller)
  • » 
    Modbus® RS-485 RTU communication
  • » 
    Standard, dust / water tight, corrosion resistant enclosure (drip proof)
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 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. The RLY comes in a standard water / dust tight, corrosion resistant ABS / polycarbonate enclosure with a hinged, secured door. 
 
A maximum of ­one RLY-4 device (offering a maximum of 4 remote relays) can be connected to the QCC. 
 
Up to fourteen RLY-4 devices (offering a maximum of 56 remote relays) can be connected to the FCS. Up to seven RLY-8 devices (offering a maximum of 56 remote relays) can be connected to the FCS.
