Description
Fixed gas detectors on a pad send a 4-20 mA signal; this controller collects those signals in one place. It shows each channel on the LCD, switches two relay outputs (horn, beacon, fan or shutdown relay) and passes the readings to a PLC, RTU or gateway over RS485.
Where it fits
- Tank batteries, compressor and pump houses with several H2S, LEL, CO or O2 transmitters.
- Control rooms and MCC buildings that need one panel for all field detectors.
- Upgrading stand-alone detectors to a central display and alarm relays.
