Multi channel gas controller for automatic online monitoring system of environmental gases，QB6000 gas alarm controller is a gas alarm controller developed by our company based on touch screen control. The controller has practical functions and is easy to operate. It can be combined with our company's gas detectors to form an industrial gas alarm system. The controller can connect 1-4 standard RS485 signals or (4~20) mA analog signals to the detector, and upload the standard RS485 signals to the upper computer, thus forming a multi-level monitoring network of remote monitoring, local monitoring, and on-site monitoring, greatly improving the real-time and accuracy of monitoring. The alarm system composed of the controller and detector can be widely used for safety detection and alarm in places that require fire prevention and toxic gas leakage prevention, such as chemical plants, oil depots, liquefied gas stations, gas stations, gas stations, paint spraying rooms, etc.
