Gas detection unit
GMA 40 Serie
GfG - Gesellschaft für Gerätebau mbH
The GMA40 system is a flexible, cost-effective control systems for DIN-rail mounting. The controllers can be clipped directly on to standard DIN rails in switchgear cabinets. As many controllers as required can be plugged together, so that voltage supply and alarms can be connected without additional wiring.
Reliable and cost-effective
Together with the appropriate transmitters, GMA40 series controllers provide a complete fixed gas detection system for a wide range of different flammable and toxic gases, and oxygen. All transmitter types can be attached. The GMA40 series controllers supply the attached transmitters with power and process input signals received.
Flexible applications
Three alarm thresholds can be individually adjusted in the GMA40 series controllers. In addition, each controller has four floating relays which can be switched normally open or closed. These relays can activate external alarm devices, or switch on ventilation, for example. Gas leaks are rapidly detected.
The advantages at a glance:
*Choice from 1 to 4 transmitter inputs
*Change-over contacts for all relays
*3 adjustable alarm threshold values
*Max/min memory
*24 V/230 V
*Single and collective alarm outputs
