Main Performance and Features:

① Branch signal transmission (4-20mA);

② 8 channels, each channel works independently;

③ LCD display, wall-mounted installation;

④ Two-level alarms: low-limit alarm, high-limit alarm;

⑤ Automatic fault monitoring:

When one of the following conditions occurs, the controller can emit fault signals that are significantly different from the gas alarm signal:

1. Short circuit or disconnection between the controller and the detector wiring;
2. Detector malfunction;
3. Controller main power or backup power failure;

⑥ Linkage output, linkage output mode and logic can be set:

Each channel has 2 linkage outputs, which can control 2 external devices (fans or solenoid valves);

⑦ Power conversion function:

Each channel has independent main and backup power supply, and can switch seamlessly between main and backup power sources, with status indication of both power supplies;

⑧ Can store 999 alarm records and 999 fault records:

Recent 999 alarm and 999 fault records can be queried, and information is not lost during power off;

⑨ Battery protection function:

When only backup power is in use and the battery voltage is low, the system will automatically shut down to protect the battery;

⑩ Equipped with RS485 bus interface, enabling communication with the host computer.
