Control module MD-2.ZA24 2 inputs, 24V power supply, 1 output for valve

Control module for gas detection systems

The MD-2.ZA24 module is a key element of gas detection systems, designed to control and power gas detectors and control shut-off valves. The device is used both in the Dual Threshold Gas Detection System and in the Active Gas Installation Safety System (ASBIG), ensuring a high level of safety in gas installations. The module allows monitoring of up to two gas detectors, alarm signaling and control of additional devices, such as acoustic and optical signaling devices.

Functionality and application

MD-2.ZA24 has been designed with reliable operation and easy integration with existing systems in mind. Its functionality includes:

• Detector control: Monitoring the status of up to two two-threshold gas detectors of the DEX/F, DG/F or DG.EN type.
• Alarm signaling: Optical signaling of the detector's alarm status and control outputs, which facilitates quick problem identification.
• Shut-off valve control: Ability to control a gas shut-off valve, which is crucial in signaling and shut-off systems in accordance with the Minister of Infrastructure Regulation.
• Contact and voltage outputs: Allow connection of additional devices, such as fans, contactors or acoustic and optical signaling devices.
• Alarm input: Possibility of integration with fire protection systems or a manual valve switch to increase safety.
• 24V DC power supply: Ensures compatibility with a wide range of devices and installations.

Thanks to this, the MD-2.ZA24 module works in various applications, from residential buildings to industrial facilities, where effective monitoring of the presence of hazardous gases and a quick response in the event of a failure are required.

Advantages and benefits

• High reliability: Ensured by a solid construction and high-quality components.
• Versatility: Ability to cooperate with various types of gas detectors and external devices.
• Compliance with standards: Meets the requirements of the Minister of Infrastructure Regulation regarding signaling and shut-off systems.
• Easy installation and configuration: Allows quick implementation of the system without the need for specialized knowledge.
• Safety: Increases the level of safety in gas installations by responding quickly to threats.
• Galvanic isolation of circuits: Provides resistance to interference and increases safety of use.
• Wired connection control: The module checks the correctness of the connection to the shut-off valve, which minimizes the risk of system malfunction.

The MD-2.ZA24 module is an investment in safety and peace of mind, both for installers responsible for installing gas detection systems and for end-users who use these systems on a daily basis. The device is characterized by solid workmanship and the possibility of integration with other elements of the safety system, creating a comprehensive solution for protection against hazards related to the presence of hazardous gases.
