Modbus IO 4G IOT Cellular Modem with 8DI 8DO 8AI Ports Wireless Network Equipment

• Introduction​ of IOT Cellular Modem
• 4G IOT Cellular Modem ZHC4941 is an industrial-grade 4G RTU that provides 8 DI, 8 DO, 8 AI and 1 RS485/232 interface, supports local logic processing operations, automatic acquisition and active reporting, Modbus RTU/TCP adaptation, and automatic threshold calibration Special functions such as reporting, configuration software docking, dry and wet node IO detection, support one-to-one, many-to-one network.

Parameters of IOT Cellular Modem

Working Mode of IOT Cellular Modem

1.HTTP Client
Support serial data transmission to designated server via HTTP.
2. TCP Client
The serial server actively initiates a TCP connection to the server. If it fails, it will continue to reconnect until it succeeds. If the connection is successful, the server and the serial device can perform two-way transparent data transmission.

• Application
• of
• IOT Cellular Modem
•  
•  
• On-site remote terminal control equipment ZHC4941 can collect data such as flow and pressure in real time, and transmits the data to the monitoring master station through GPRS or 4G wireless communication network. The master station receives, stores, analyzes and organizes the monitoring data, and controls the valve or Start and stop the pump, and produce various monitoring data lists, reports and comparison curves. Customers can query monitoring point data through PC or mobile.
