GDA 40126 : Flammable Gas Detection Controller
Discontinued Product
The GDA 40126 Gas Detection Controller is a standalone gas detector unit with inbuilt display, sounder, flasher, relays and alarm driver. Available for Flammable gases such as LNG, LPG, Propane, Hydrogen, Acetylene, Solvents, and other flammable vapours. Designed to be used in Non-hazardous areas with the GDA 2500 series easily replaceable sensor modules.
Designed, manufactured and supported locally in Australia.
Note
This product is being replaced by the SENKO SI-100-009 Combustable Sensor
The GDA 40126 has 2 user relays which can be programed to operate at any level within the gas detectors operational range as well as an independent fail safe fault relay. The unit's alarm state is indicated by the display and by flashing LEDs additionally there is an o/p to drive a 24 VDC sounder / flasher (AVR-20) all of which can be muted from the front panel.
- Gases available Methane, Propane, Butane, Acetylene, Hydrogen, Solvents and others on request
- 24 VDC operation with optional plug mounted power supply
- 4-20 mA o/p and optionally Modbus o/p
- Backlit LED display
- Real time display of gas concentration
- Mutable internal sounder
- 2 User selectable/ configurable alarm relays (SPCO)
- Alarm relays are inhibited during calibration.
- External Mutable drive for AVR-20 series sounder / flasher unit.
- 1 Fault relay (SPCO)
- Australian Factory Certificate of Calibration
Poisoning: GDA sensors are designed to operate in a wide range of harsh environments and conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage and operation.

This sounder/flashers operates at 24VDC. The sounder can be permanently disabled so that unit acts as a flasher only. These units are designed for internal use. These are available in Red or Amber.
CALGAS : Calibration Gas
To test and maintain accuracy gas detection systems require regular testing and calibration. GDA can provide you with a complete line of calibration equipment to calibrate all of our gas sensors and detectors. Our calibration gas cylinders all come with N.I.S.T. certification and ISO 17025 approval so you can be confident that you will receive gas with the highest accuracy levels.
iGas : iGas Portable Detector
The iGas Detector CO2 is a portable single gas detector designed to detect the presence of carbon dioxide in ambient envirornment. When activated, iGas CO2 continuosly monitors ambient air for the pressence of carbon dioxide gas and alerts the user to potentially unsafe exposure with LED, vibrating and audible alarms.
