Pollution source data acquisition instrument / operation and maintenance platform SLH-SCY1909
Data acquisition instrument, including 6 RS232 serial ports, 1 RS485 serial port, 8 4-20mA analog signal input ports, and 4 switch input ports. Among them, 6 digital communication ports RS232 are used to communicate with intelligent instruments with similar interfaces and read the data of the instruments. Such instruments include COD online monitor, ammonia nitrogen online monitor, total phosphorus online detector, heavy metal ion online Monitors, flow meters, etc.
If some instruments have RS485 interface, you can directly use the RS485 serial port of ZZ-5100 to read data. 8 4~20mA input ports, used to connect standard 4~20mA transmitter current signals, such as some models of PH meters, flow meters, pressure transmitters, etc., can also be connected to current transformers to measure environmental protection facilities Operating current, so that the operating power of these environmental protection facilities can be monitored.
Communication protocol: in line with HJ/T212 requirements
Real-time sampling and monitoring
