GDA 40125 : Toxic/Oxygen Gas Detection Controller (4-20 mA o/p)

The GDA 40125 units are an integrated, wall mounted single gas detector control unit with a display. They interface with the full range of GDA 2500 series Toxic and Oxygen gas sensors. The unit has 2 user relays which can be programmed to operate at any level within the gas detectors operational range. Additional to this there is an independent fail safe fault relay. There is an o/p to drive a 24 VDC sounder / flasher (AVR-20Y/R) which can be muted from the front panel. The alarms are indicated on the display and by flashing LEDS. There is also a facility for modbus connection which can be added to the GDA 401205.
