Conex DIS-G

Product catalog summary

Overview: The document provides technical specifications and features of the Conex® DIA-G and DIS-G gas warning systems, designed for monitoring gas dosing installations and storage rooms. These systems are crucial for ensuring safety by detecting hazardous gas concentrations.

Conex® DIA-G Features:

Monitors two different gas storage rooms or gases simultaneously.
Displays both measured values concurrently.
Ensures safety with permanent sensor monitoring, alarm relay, and optional backup battery operation.
Quick response to sudden gas concentration changes.
Long sensor service life with auto-calibration and monitoring.
Separate sensor interface allows installation up to 500 m from the sensor.
Optional audible and visual alarms.
Supports multiple languages: German, English, French, Spanish, Polish, and Russian.

Conex® DIS-G Features:

Monitors two gases simultaneously.
Displays both measured values concurrently.
Automatic sensor test function for safety.
Quick response to sudden gas concentration changes.
Long sensor service life.
Optional audible and visual alarms.
Supports languages: German, English, and French.

Technical Data:

Both systems use a 16-bit microprocessor system and I2C bus technology.
Display: Backlit plain-text for DIA-G; LCD for DIS-G.
Relay outputs: Five potential-free relay outputs, switchable to NO or NC.
Signal inputs and outputs: Two measured value inputs and two current outputs for DIA-G; two analog outputs for DIS-G.
Safety functions include permanent sensor monitoring and wire breakage monitoring.
Operating temperature: 0 to +50°C for DIA-G; 0 to +45°C for DIS-G.
Power supply: 110-240V for DIA-G; 230/240V or 115/120V for DIS-G.
Enclosure class: IP 65 (wall-mounted).
Weight: Approx. 1.5 kg for DIA-G; 0.8 kg for DIS-G.

Gas Sensors and Measuring Parameters:

Potentiostatic sensors measure Cl₂, ClO₂, O₃, NH₃, and HCl with varying ranges and response times.
Amperometric sensors measure Cl₂, ClO₂, and O₃ with a range of 0 to 5 ppm.
Expected sensor life varies from 12 to 24 months depending on the gas type.
Permissible operating temperature ranges from -20 to +40°C for potentiostatic sensors and +5 to +45°C for amperometric sensors.
