GDS XDI-F1 Hazardous Area Gas transmitter

The GDS XDI-F1 Gas Transmitter is capable of utilising a wide range of sensor cell types offering an unmatched number of gases that may be monitored. Standard 4-20mA signalling with CAN Bus address enables the sensors to be networked via the GDS Combi control system or customer preferred monitoring systems.

The GDS XDI-F1 is capable of independent operation or multi-point system configuration networking several gas detectors back to a central control panel. With optional on-board relays, the monitor has the added ability of stand-alone operation, activating alarms, horns, or fans and can also shut down a system without the need to wire back to a central control panel. The XDI-F1 also offers a relay deactivation feature to prevent accidental alarm activation during calibrations. The units also feature simple non-intrusive calibration, easy to read display, programmable alarms and on-board sensor life indicators.

The GDS XDI-F1 Gas Transmitter is designed to operate in hazardous and tough environments protecting the safety of your people and facilities.
