PolyGard®2 Gas Controller GC-06-XXXXXX-00 GasAlarm

Measuring, warning and controlling module for toxic, combustible and refrigerant gases and vapours.

The gas controller series GC-06 can monitor and evaluate up to 100 gas sensors, 96 of them PolyGard®2 digital and / or 4 of them analog 4-20 mA sensors. Four free adjustable alarm thresholds are provided per sensor. For the alarm messages the controller offers four alarm relays with potential-free change-over contact and two analog outputs with 4 to 20 mA signal. With the extension modules EP-06 the Gas Controller can manage up to 32 analog gas sensors, 32 alarm relays and 16 analog outputs. For the main and field bus outputs there is an integrated overload and reverse polarity protection.

The GC-06 series is equipped with a self monitoring system with integrated hardware watchdog and with a power failure message as well as with a functional control of the registered digital / analog sensors according to the requirements of the gas measuring technique.

APPLICATION

The GC-06 gas controller series is used for the monitoring and warning of toxic and combustible gases and vapors as well as of Freon refrigerants within a wide range of the gas measurement technique. Numerous adjustable parameters and set-points permit individual adaptation to many applications.
