MODBUS RTU IOT Cellular Modem

RS485 MODBUS RTU IOT Cellular Modem With Digital Input Output Ports

• Introduction​ of IOT Cellular Modem

ZHC2921 is a network IO product that supports 4-channel dry (wet) node detection, 4-channel relay (COM, NO, NC) output, 4-channel analog (current 4~20mA) detection, and 1-way serial port passthrough transmission. It is compatible with Modbus RTU/TCP protocol.With the function of "remote control" as the core, it is highly easy to use, and users can easily and quickly integrate into their own system to realize the remote control based on GPRS network.

  The field all-in-one fertilizer and water machine is connected to RTU, which collects the data of the controller and sensor via Modbus TCP, preprocesses the local storage and uploads the data via 2G.The cloud platform monitors the information of the fertilizer and water integrated machine in real time, and realizes the remote automatic control of the computer and mobile phone.If the machine fails, the alarm will be sent to the management personnel's mobile phone through RTU to achieve rapid early warning processing and reduce the failure.Irrigation and fertilization equipment combined with irrigation and fertilization system, through the data analysis of various sensors, scientific and reasonable arrangement of irrigation and fertilization plan, timing and quantitative, time temperature control, accurate proportion, combined with the most advanced irrigation control system, to achieve the precise control of irrigation amount, fertilizer amount and water and fertilizer application time.
