The GDA 4020 control unit has 2 x 4-20 mA i/p with 3 associated programmable relay alarm levels per sensor. There is an independent fault relay. There are 3 x analog o/p’s which can be configured for either channel as 4-20 mA, 0-20 mA, 0-5 V or 0-10 V. The controller has an isolated RS485 o/p which can be configured to drive modbus or an interface to the M2001 mimic panel. All configurations are carried out via the front panel push buttons. The unit requires 24 VDC.

Designed, manufactured and supported locally in Australia.

GDA 4080: 8 Channel Gas Detection Controller

The GDA 4080 Gas Detection Controller is designed to be to take up to 8x 4-20 mA sensor inputs and display the gas readings of the individual sensors. The multi-colour display will indicate the alarm status, levels and faults.

Designed, manufactured and supported locally in Australia.

GDA 2400: Multiplexed 8 Channel Gas Detection Controller

The GDA 2400 control unit caters for up to 8 GDA Sensors. The controller selects the highest reading from the sensors and displays the highest reading and is used when all the gas sensors are the same type.  It is particularly useful in Periphery monitoring and Car park ventilation control.
