PBX-COMBI6C is a compact analogue control panel designed for evaluating signals from gas detectors and controlling associated safety systems. It allows the connection of up to 6 detectors with a standardised analogue output of 0–10 V. Ideal for monitoring concentrations of CNG (Compressed Natural Gas) and other flammable or toxic gases in industrial facilities, boiler rooms, or garages.

Key Features

• Support for up to 6 independent analogue inputs (0–10 V).
• 4 relay outputs for controlling ventilation, signalling, or safety elements.
• Integrated LCD display with clear display of values and statuses.
• Adjustable concentration threshold values for automatic output switching.
• Acoustic and visual signalling of faults and limit exceedances.
• Easy installation and simple parameter setting directly on the device.

Applications

The PBX-COMBI6C control panel is intended for applications where continuous monitoring of CNG and other gas concentrations is necessary, and automatic control of safety elements is required. Ideal for:

• Gas boiler rooms
• Underground garages
• Technological operations with gas leak risks
• CNG filling stations

Advantages

• Flexible connection of various types of detectors.
• Reliable and fast evaluation of current states.
• Local alarms without the need for connection to a superior system.
