Touch screen 128 channels gas alarm controller with RS485 connection and datalogger
Product description
Bus system 128 channels controller is a simple and practical controller that can connect 128 detectors.The system is compatible with all kinds of gas detectors. The 7-inch touch screen shows local time, detection gas, gas concentration , gas concentration unit and whether the current detector is in good condition in real time. When the gas concentration reaches the preset alarm value, it generates sound alarm. The controller can keep 1000 gas alarm records, which is convenient for users to keep track of the detector alarm status at any time.
