Addressable control units MDD-1x/T

The MDD-1x/T digital executive units are part of the Digital Gas Detection System (DGDS). They allow to control a single threshold detector produced by GAZEX and connect it to the DGDS.

MDD-1x/T are devices dedicated to work with MDD-256/T type supervisory control unit. Communication is carried out in industrial standard RS-485.


  • power supply and control of one DEX/F, DG/F, DG.EN or DEX/A detector;
  • detector’s power supply can be switched off (via the function switch);
  • communication, control and information transfer between system components in RS-485 standard (MODBUS RTU protocol);
  • removable, screwless terminals, possibility of using wires with single or multi-strand wires (without crimping sleeves) – quick installation, easy maintenance;
  • power supply 24VDC;
  • mounting on TS35 rail in standard electrical switchgears;
  • configuration of unit settings via dedicated configuration software „DETnet View”, available at
