Description
The GDB12 gas alarm controller monitors gas concentrations in ambient air, compatible with various gas types and enabling centralized control across multiple points. Featuring a microprocessor control unit, it displays real-time gas concentration on the screen. When detected concentrations reach or exceed preset alarm thresholds, the controller activates audible and visual alerts. Equipped with multiple passive contact sets and independent AC220V/DC24V pulse outputs, it drives ventilation systems or closes electromagnetic valves. The controller also includes backup battery support for enhanced reliability.
The controller is widely used in industrial and commercial gas leakage detection and monitoring, can effectively prevent poisoning accidents, explosion and fire, so as to ensure the safety of life and property.
Key Features
- The controller is easy to operate and the whole machine is light
- Built-in microprocessor with rich software features
- It supports real-time sampling of detector signals and real-time data calculation
- System self-diagnosis, power management, alarm display, and peripheral driver functions
- It can manage and process detectors with different gas types, ranges, and data units.
- It has two sets of digital control outputs and two sets of pulse signal outputs, which is convenient for external linkage control devices.
- History storage for easy retrieval
- The system features an upload interface that enables real-time data transmission via RS-485 signals, meeting the needs of most clients.
- The installation is simple. Just fix the bracket on the wall and hang the controller.
- Manual screw cap design
