ACR4000 combustible gas detection controller is a multi-channel wall-mounted controller, easy to install and set. It adopts a 10-inch color touch screen, has a buzzer and status indicator lights, and can output switch signals. The controller can display the concentration information of combustible gas on site in real time, and send out an alarm when the concentration exceeds the standard or the sensor fails, and record the alarm information for query.
1. The core of the controller adopts advanced ARM processor.
2. The display is intuitive and easy to understand, and the operation is convenient.
3. Intelligent protection system.
4. Password protection. Each level of operation has corresponding passwords, effectively avoiding misoperation.
5. With RS485 communication interface, it can flexibly communicate with the graphics software of the upper computer.
6. Optional combustible gas monitoring software.
