Gas Detector Controller is a cost-effective and practical gas monitoring device, mainly suitable for small and medium-sized industrial projects that require zone interlocking functions, such as small and medium-sized workshops, warehouses and production lines. It is equipped with a Chinese/English LCD display that supports two-language switching, making debugging and operation simple and convenient, and can clearly display the installation location of each device, facilitating on-site management.
Zone Alarms & Interlocks
Quickly triggers alarm signals and interlocking controls when gas concentration exceeds safe limits, preventing industrial safety accidents.
Dual-Language LCD Display
Features a 3.2" Chinese/English LCD screen for easy configuration, showing real-time location and status of every detector.
Flexible Protocols (XBUS/HBUS)
Utilizes XBUS 2/4 wire protocol for easy wiring, and remains compatible with HBUS to easily upgrade older systems without full replacement.
IoT Wireless Options
Supports optional WiFi, NB-IoT, and 4G wireless gateways, enabling remote system monitoring, data viewing, and notifications.

Frequently Asked Questions (FAQ)
What is the maximum channel capacity supported by the JB-TB-AT2020S Gas Detector Controller?
The controller supports a maximum capacity of 32 channels on a single circuit.
What is the maximum transmission distance for wiring?
The controller supports a maximum transmission distance of up to 1500 meters using the XBUS 2/4 wire protocol.
Can I upgrade my existing control system without replacing all elements?
Yes. The device is fully compatible with the HBUS protocol, allowing you to upgrade existing damaged controllers directly without replacing the entire monitoring system, which significantly lowers replacement costs.
Does the device support remote monitoring and IoT connectivity?
Yes, an optional wireless gateway is available for IoT transmission, offering WiFi, NB-IoT, or 4G connectivity options for remote data viewing and alarm notifications.
What display and languages does the controller interface support?
The controller features a 3.2" dot matrix LCD display that supports dual-language switching between English and Chinese.
What type of relay output and programming capabilities does it offer?
It features two groups of built-in passive outputs (DC24V/2A or AC220V/1A) with adjustable output types (Hold/Pulse) and a built-in passive switch input, allowing for programmed control of external outputs through interlocking functions.
