BX480-AX

4 channel gas detection controller Atex certified

II (2) G EN 60079-29-1

Through the connection of 4 remote sensors, the BX480-AX control panel, ATEX certified, has been designed and built according to European regulations to detect the presence of toxic and/or explosive gas in a flexible way

A microprocessor is used to create a complete surveillance and control system with maximum flexibility.

Thanks to this and its other features, the BX480-AX is suitable for civil and industrial applications.

The BX480-AX control unit has two hazard levels:

  • 1st LEVEL, 1st Pre-Alarm 13 % L.E.L/200 ppm.
  • 2nd LEVEL, Main Alarm at20% L.E.L./300 ppm.

Other technical features make this gas controller extremely versatile and reliable; for example, by using a series of micro-switches it is possible to:

  • Select or disable a sensor when not installed or faulty;
  • Select the gas type to be detected (toxic or explosive);
  • Choose the relay functioning mode (pulsed or continuous);
  • Choose deadband exclusion mode.
