Conex® DIA-G, 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 capable of monitoring gases such as Chlorine (Cl2), Chlorine Dioxide (ClO2), Ozone (O3), Ammonia (NH3), and Hydrochloric Acid (HCl).

Conex® DIA-G Features

Monitors two different gas storage rooms or gases simultaneously.
Displays both measured values simultaneously.
Ensures safety with permanent sensor monitoring, alarm relay, and optional backup battery.
Quick response to sudden gas concentration changes.
Long sensor life with auto-calibration and monitoring.
Separate sensor interface allows installation up to 500 meters 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 simultaneously.
Automatic sensor test function for safety.
Quick response to sudden gas concentration changes.
Long sensor life.
Optional audible and visual alarms.
Supports languages: German, English, and French.

Technical Data

Both systems use a 16-bit microprocessor system with I2C bus technology.
Display: Backlit plain-text display (DIA-G) and LCD (DIS-G).
Relay outputs: Five potential-free relay outputs, configurable to NO or NC.
Signal inputs and outputs: Two measured value inputs and two current outputs (0/4-20 mA).
Safety functions include permanent sensor monitoring and wire breakage monitoring.
Operating temperature ranges from 0 to +50°C for DIA-G and 0 to +45°C for DIS-G.
Power supply options vary between systems, with DIA-G consuming approximately 20 VA and DIS-G approximately 5 VA.
Both systems have an enclosure class of IP 65 and are wall-mounted.

Gas Sensors

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 0-5 ppm and a response time of 2 seconds.
Expected sensor life ranges from 12 to 24 months depending on the gas type.
Operating and storage temperature ranges are specified for each sensor type.
