DG-0E.HCN/M Digital RS-485 output

Product model withdrawn from sale

Device group: Threshold gas detectors
Device type: DG/M

Digital detector type DG/M is designed for continuous monitoring of the concentration of specified gas on the premises monitored by Digital Gas Detection System. When the concentration exceeds a preset threshold, the detector produces a signal in the system via RS-485 network and switches on built-in LEDs.

Detector can be equipped with a semiconductor, electrochemical or Infra-Red sensor.

The detector has a removable module with the intelligent sensor, which facilitates maintenance and lowers operating costs. Detector DG/M cannot be used in hazardous locations.

Scope of application

  • industrial areas, factories, logistics centers, public buildings
  • dispersed gas detection systems


  • communication, control and transfer of information through the port RS-485 with MODBUS RTU protocol;
  • short response time;
  • gas sensor in intelligent, EXCHANGEABLE module;
  • built-in microprocessor control provides reliability, stability, thermal compensation system, the history of alarm, semi-automatic address control;
  • 3 or 2 alarm thresholds mode or gas concentration measurement mode;
  • optical signaling (4x LEDs); fast removable connection pins for FTP type cables;
  • splash-proof case (IP44)
  • 2 cable glands enabling easy connection of multiple detectors in series;
  • optional: additional steel pipes cover (AR-1d) or the duct-mouting casing (version DG…/Mw);
  • all detectors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No AP150).
