Gas detection control unit allowing connection of 4 up to 8 flammable toxic gases or oxygen detectors (through optional board) with 4-20 mA proportional output. For each input it is possible to set the type of detector, suitable measure range and alarm level values. Concentration values measured are shown on a backlit liquid crystal display. The control unit has 4 relay outputs, associated to: Malfunction, Alarm 1, Alarm 2, Alarm 3 + 1 auxiliary output that can be associated to one of the four statuses above. By adding an optional module, in addition to the 4 inputs it is possible to implement 16 open collector outputs
