Control module MD-1.A24 1 input, 24V power supply

Gas detection system alarm module

The MD-1.A24 control module is a key element of signaling and safety systems in gas installations. Designed to work with DEX/F, DEX/A, DG/F or DG.EN gas detectors, it provides reliable control and power to one detector. The device is used both in the Dual Threshold Gas Detection System and in the Active Gas Installation Safety System type GX (ASBIG).

Functionality and application

The MD-1.A24 module allows monitoring of the gas detector status, alarm signaling and control of external devices. This allows the installer to build a comprehensive gas leak warning system, and the end user to gain confidence in the safe use of the installation. The device has an alarm input, which allows integration with fire protection systems or a manual valve shut-off. Switching outputs allow control of fans, contactors or information boards – increasing the functionality of the entire system.

Key features and benefits

• Versatility: works with various types of gas detectors (DEX/F, DEX/A, DG/F, DG.EN), providing flexibility in the selection of system components.
• Alarm signaling: provides optical signaling of the alarm status of the detector and control outputs, making it easier to react quickly in the event of a threat.
• Galvanic isolation: input and output contacts are galvanically isolated, which increases safety and resistance to interference.
• 24V= power supply: allows easy integration with existing 24V DC power systems.
• Compact dimensions: dimensions 165 x 190 x 90 mm allow mounting in a limited space.
• Emergency output: informs about the emergency status of the module or lack of power – important for diagnostics and system maintenance.
• Expandability: possibility of powering an additional module for remote valve control (in combination with appropriate models).

The MD-1.A24 module supports one detector, has two 12V= alarm control outputs, two switching contact outputs and one alarm input. The power supply is 24 V=.

The MD-1.A24 module complies with the requirements of the Regulation of the Minister of Infrastructure of the Republic of Poland of April 12, 2002, which guarantees its admissibility for use in signaling-shut-off systems. This is a solid solution for installers and users looking for a reliable gas detection system.
