Multi-channel gas detection control unit GMA200-MW4

LCD display

Wherever gases are used or may be present in industrial and commercial applications, they must be monitored. A gas detection system consists of one or more transmitters which use sensors to detect gases and a controller which has a wide range of tasks. The GMA200-MW4 controller is ideally suited for complex gas detection systems with up to 16 transmitters (up to four of which can be analog). Safety measures can be connected directly to the GMA200-MW4 via internal relays. The display will indicate the current measured values as well as any alarms or special states of the transmitters. Fixed transmitters monitor combustible or toxic gases and vapors present in the ambient air as well as the oxygen concentration. A controller displays the measured gas concentrations centrally and processes the incoming signals. The GMA200-MW4 is the right choice if you need to monitor gases with up to 16 transmitters (up to 4 of which can be analog) you want safety measures to be operated directly via the controller the measured values need to be displayed centrally an acoustic and visual alarm is required on site you want the operating status and alarms to be indicated by status LEDs Versatile application possibilities The GMA200-MW4 controller and the connected transmitters form a fixed gas detection system for measuring toxic and flammable gases as well as the oxygen concentration. Up to 16 digital transmitters can communicate with the controller using the RS-485 interface. Analog transmitters (up to 4) can be connected on 0.2-1 mA or 4-20 mA lines. The GMA200-MW4 is suitable for all GfG transmitters and available gas types.
