GFG gas detection system

Listing ID #4357580

The gas detection controller GMA200continues with the tradition of the company under consideration of innovative technology and trend-setting flexibility. It is designed for commercial and industrial applications for the measurement of combustible and toxic gases as well as for the measurement of oxygen. The compact construction of the GMA200-MW4provides a cost-efficient solution for safe gas monitoring of industrial facilities.
Parallel Measurement and flexible application
Up to four analog and 16 digital transmitters can be connected to GMA200-MW4 and monitored simultaneously.Via the configuration software the measurement range, the measurement designation, the type of transmitter and the type of gas can be set individually as well as three alarm thresholds can be programmed for every connected single transmitter.The microprocessor of the GMA200-MW4 evaluates all receiving signals and activates alarm and relays. In doing so one single gas detection controller GMA200-MW4 can master different gas detection tasks.
Integrated Relays
Permanent increasing demands on safety measures require complex gas detection systems and redundant protective measures to protect from gas hazards.Therefore the GMA200-MW4 has six internal relays. For the implementation of safety measures and alarm, four relays can be programmed freely so that in case of alarm the safety measures can be triggered automatically. The programming grants wide-ranged and flexible possibilities like allocation of one or more measurement point s to relay,single alarm per measurement point,configuration of collective alarm and group alarm, error report and voting function. For each, safety related error report and maintenance, one further relay is available.
Graphic display
The clear conception of the controllerGMA200-MW4 allows the rapid recognition of hazardous situations. Current measurement values are shown continuous on the LCD- graphic display.At Alarm a red back light is active.
