PolyGard Digital Transmitter DGC DT-02

Transcription

1 PolyGard Digital Transmitter DGC DT-02 Description LON interoperable digital gas transmitter to monitor toxic and combustible gases and vapors in the ambient air. The complete monitoring and alarm tripping is integrated in the transmitter. Due to the great number of parameters a convenient and flexible adaptation to the most different service conditions is possible. For normal applications, however, standard values are deposited as defaults. The simple and quick commissioning is performed via the autarkical DGC- STL service tool. In conjunction with the digital output modules DGC- DIO and DGC- ECS a very flexible installation is possible. In addition the DGC- DT is equipped with a 4-20 ma input for the connection of an analog gas transmitter. Alternatively the DGC- DT can also manage LON systems via the LON interoperable interface in the interoperable mode. Stainless steel housing Application To sense toxic and explosive gases in a wide variety of commercial applications such as vehicle exhaust in parking structures (e.g. underground garages), engine repair shops, tunnels, equipment rooms and ventilation systems, garages, shelters, loading bays, go-kart race courses, boiler rooms, etc. and to transmit the signals to any compatible interoperable LON bus system.
