The GD900 DIN rail gas detection control unit, from Gas Detection Australia , has been specifically designed for system integrators.
The unit is a 22.5mm B35 DIN rail mounted single channel control unit that can accept inputs from any 4-20mA transducer or sensor. It has two user- set alarm points and can be easily configured as positive or negative alarms.
Three volt-free relay contacts are available with LEDs indicating the alarm condition. They are Al1, Al2 and Fault The alarm conditions on the GD900 DIN rail gas detection control unit can be latched or non-latched, with the latter not requiring any user intervention to RESET once the signal level is below alarm threshold.
The GD900 DIN rail gas detection control unit is available in both 12V d.c. and 24V d.c. versions. It includes a self test facility and is C.E. tested.
The GD900 DIN rail gas detection control unit easily integrates with all GDA 4-20mA gas detectors.
