Model GDA 4288 -8 Channel Gas Detection Controller

There are 8 fully user configurable relays; and an additional fault relay. The GDA 4080 has a compliant MODBUS interface allowing all of the controller’s information to be read into a BMS systems. The system has an independent two wire comms system to drive remote mimic panels which indicate the current gas levels in their associated area. It is housed in an enclosure with a swing door making cable access and servicing easy.
