DG-4E/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

Features

• 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)
