Coordinate gas detector alarms through a central controller selected for the site network.
A bus-oriented configuration supports multiple compatible field detectors.
Configurable thresholds and programmable relays support a defined response.
The display and event view help operators check alarms and faults.
Confirm bus topology, channel count and power options against the exact GDB10 version.
The GDB10 Gas Alarm Controller (hereinafter referred to as the Controller) is a product developed by our company, capable of processing multiple 4~20 mA/RS485 signal channels simultaneously. It features excellent stability, high accuracy, and intelligent parameter configuration. With abundant external control ports, users can freely select detector types and connection ports, enabling on-site monitoring and alarm systems through simple setup and wiring.
The controller is primarily used for monitoring flammable gases, displaying numerical indicators of the gas to be tested. When the concentration of a specific gas under test at the site fails to meet the preset standards, the system automatically triggers a series of alarm actions, such as audible alarms, exhaust ventilation, or tripping (depending on user configurations).
Years of market application have demonstrated that this product features user-friendly design, outstanding performance, stable and reliable operation, convenient installation and maintenance, as well as comprehensive gas measurement capabilities. It fully meets the requirements of industrial safety monitoring for high equipment reliability, operational stability, and diverse gas measurement options.
Gas alarm controllers are widely used in industries such as military, mining, healthcare, petrochemicals, metallurgy, animal husbandry, refining and chemical processing, gas transmission and distribution, production process control, environmental protection, and water treatment.
