Control module MD-2.A24 2 inputs, 24V power supply

Gas detection control module – reliable installation protection

The MD-2.A24 control module is a key element of gas detection systems, designed to monitor and power dual-threshold gas sensors. The device provides comprehensive protection by controlling up to two detectors and enabling integration with fire alarm systems and other safety devices. It is an ideal solution for both professional installers and end-users looking for a reliable and precise alarm system.

Functionality and application

The MD-2.A24 module finds wide application in gas detection systems, such as the Dual-Threshold Gas Detection System and the Active Gas Installation Safety System type GX (ASBIG). It allows monitoring of gas concentration in various spaces, ensuring a quick response in case of exceeding permissible norms. Thanks to the ability to control external optical and acoustic signaling devices, as well as cooperation with other devices via relay outputs, the MD-2.A24 is an integral part of a comprehensive safety system.

• Detector control: The module supports up to two dual-threshold gas detectors of type DEX/F, DG/F or DG.EN.
• Alarm signaling: Provides optical signaling of the detector's alarm status and control outputs.
• System integration: Has an alarm input for cooperation with fire alarm systems or a manual valve shut-off.
• Device control: 12V= alarm outputs allow powering additional acoustic and optical signaling devices, and relay outputs are used to control fans, contactors or information boards.
• Fault information: The "FAULT" relay output informs about the module's emergency state or lack of power.
• 24V DC power supply: Provides a stable power supply for connected detectors and devices.

Construction and user features

The MD-2.A24 is characterized by a solid construction and high functionality. The housing made of ABS provides protection against external factors (IP54), and the possibility of mounting on a TS35 rail facilitates installation in electrical panels. The module is equipped with removable connectors, which simplifies the connection of single- and multi-strand wires without the need for ferrules. Additionally, the module has a built-in load and wired connection control to ensure proper operation of dual-threshold detectors.
