GMA 40B Series Fixed Controllers, Fixed Systems Gas Detection, GfG Instrumentation
Gas Detection Systems
The GMA 41 1-channel controller and the GMA 44 4-channel controller are an integral part of safe and reliable gas warning systems.

  • Intuitive push-button operation
  • User-adjustable alarm hysteresis
  • Easy installation on standard DIN rail
  • DIN rail power supplies available
  • 4 to 20 mA output (GMA 41B only)

Every alarm in the GMA can be individually adjusted. False alarms are eliminated with the adjustable alarm delay. The point values can be freely adjusted within the detection range. They can also be adjusted later with the control keys to adapt to changing requirements. Every point value can be selected to be latching / non-latching or resettable/non-resettable.

The controller provides four voltage-free relays for the three alarms and one fault warning. The relays may be used to control additional alarm devices like lights or horns. They can even prompt specific counter measures to prevent or limit dangers from gases or vapors.
