System Overview
The S-SCCM water quality monitoring station has one ModBus RTU main station interface (which can be connected to our company through this interface)
485 transmitter: capable of monitoring water temperature, water level height, ammonia nitrogen ion concentration, pH, dissolved oxygen concentration, conductivity, and water turbidity; At the same time, the water quality monitoring station can be equipped with 485 transmitters according to the customer's own needs, not limited to default 485 devices, with 2 relay outputs; The water quality monitoring box can be connected to a network video character superimposer and a 4G router, and can be expanded to accommodate camera devices; Expandable seven inch touch screen for on-site display; This device can upload data to the monitoring software platform through GPRS or connect to the local area network through a network port. At the same time, the water quality monitoring station also has a ModBus RTU slave interface that can upload data to the customer's monitoring software or PLC configuration screen through 485 communication; The water quality monitoring station can also be connected to an external LED screen display (default dot matrix number 96 * 48).

1. Features

• It has one ModBus RTU main station interface that can be connected to our company's 485 transmitter. The default values are: water temperature, water level height, ammonia nitrogen ion concentration, pH, dissolved oxygen concentration, conductivity, and water turbidity. At the same time, other 485 transmitters can be freely matched according to customer needs.
• Two relay outputs can be associated with any signal acquisition for alarm or automatic control purposes.
• 1 multi-functional GPRS communication interface, simply insert a SIM card to upload data to the remote monitoring software platform.
• 1 RJ45 network port, capable of uploading monitoring data to a remote monitoring software platform.
• Equipped with one ModBus RTU slave interface, it can be connected to the user's own monitoring host externally PLC、 Configuration screen or configuration software.
• It can be connected to one outdoor LED monochrome display screen, with a default dot matrix of 96 * 48 (supporting a maximum dot matrix of 1024 * 256).
• Multiple measurement elements can be freely combined.
• Can be paired with solar panels and batteries for field measurement and solving power supply problems.
• It can support dual power supply of mains electricity and solar energy, ensuring that the equipment can work normally and uninterrupted even in harsh conditions.
• The device has a unique 8-bit address, which is easy to manage and identify, and can be paired with various software platforms provided by our company.
