GDS101 Gas Detection System
The GDS101 is a standalone, self-contained single channel control unit for the detection of Toxic, Oxygen or Flammable gases. The control unit is fully conﬁgurable for a single input from either a 4~20mA transmitter or a 3 wire mV device, with internal, aspirated or remote sensor options.
The GDS101 also has the capability to form part of our Combi CANbus addressable network, therefore offering the features of our most advanced gas detection system.
