Touch screen 128 channels gas alarm controller with RS485 connection and dataloggerProduct descriptionBus 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. Characteristics & Functions
•Advanced microprocessor technology
•7 inch touch screen operation
• Good stability, high precision
·Universal, RS485 signal input
• High brightness touch screen display, with two alarm functions
• 3 channesl relays and 1 common relay output
• Display local time, type of gas detected, gas concentration, current detector status, etc in real time
• standard RS485 signal output (optional)
