RS485 To GPRS IOT Cellular Modem GSM M2M Gateway For Data Transmission
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.
Parameters of IOT Cellular Modem
Intelligent agricultural irrigation
RTU ZHC2921 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.
System function
Support centralized equipment management, remote maintenance, program update
Support historical data query, historical data export
System authority management, support hierarchical authority working mode
Support fault alarm, mobile APP/PC remote control
