Description

The GASMAX GX gas monitor is an ideal solution for fixed ambient gas detection applications. The monitor is designed to detect a wide range of toxic and combustible gases in potentially hazardous environments. The monitor operates on +12 to +35 volts DC and outputs an industry standard 4-20mA analog signal. Optional programmable alarm relays and MODBUS serial slave interface allow the GASMAX GX to operate with a wide range of industry devices and system controllers.

The GASMAX GX supports both local and remote electrochemical, PID, infrared or catalytic bead sensors. Several electrochemical sensors, including hydrogen sulfide and ammonia, are available in low, medium and high ranges.

In addition to an industry-standard 4-20mA current loop output, an optional RS-485 two-wire MODBUS® interface with optional two SPDT relays are available to communicate with controllers or drive local alarm indicators. When used with the any controller’s MODBUS master port, multiple GASMAX GX monitors can be daisy-chained up to 500m to minimize wiring. A special Modbus Wiring Junction Box option makes it possible to easily create the daisy chain wiring for power and Modbus signal.

The GASMAX GX can also be fitted with a 900 MHz or 2.4 Ghz radio that will allow it to communicate with compatible GDS Corp wireless controllers and alarm stations.
