IoT RTU Master

Model: AB225M (Option without module LTE)

IoT RTU Master is a multifunctional industrial-grade wireless loT gateway terminal device. Which integrated Ethernet module and RS485, can be used for expansion to realize industrial field data access. Third-party SCADA software, PLC, HMI equipment can also be connected to the loT cloud platform to directly monitor, manage, and set up for remote terminals through cloud APP and Web interfaces, so as to realize remote industrial site monitoring. It is widely used in UAV room, water pump control, sewage treatment, meteorological environment, intelligent breeding and other occasions.

Main Features

  1. Ethernet port (RJ45) interface, supports the network port to collect PLC data through Modbus TCP protocol and upload it to the cloud;

  2. RS485, support Modbus Slave and Modbus RTU Master protocol, can expand 320 data points;

  3. Built-in TCP/IP protocol stack, support Modbus RTU/TCP, MQTT and transparent transmission;

  4. Support Modbus RTU/TCP and MQTT protocol mutual conversion;

  5. Built-in TCP monitoring port, which can be used as TCP Server, supporting up to 5 terminal access;

  6. Wide working voltage design, support 9~36VDC power supply, and with anti-reverse connection protection design;

  7. Complete anti-drop mechanism to ensure that the data terminal is always online, and the data is retransmitted when the connection is dropped.




Intelligent breeding, smart greenhouse, smart electricity, weather station, unattended computer room, smart factory, environmental monitoring.
