Wireless Data Acquisition Module 4G IoT RTU S271 is a wireless industrial IoT data monitoring and remote control unit, which is an ideal solution for remote data monitoring, data acquisition, remote control, and real time alarm.

The remote data acquisition module features 4 digital inputs, 4 analog inputs, 4 relay outputs, 1 temperature and humidity input, and when a sensor is abnormal and causes an alarm, the RTU will notify users by SMS, dialing, and also uploading data to cloud platform, monitoring center.

The IoT RTU supports Modbus RTU over TCP protocol, Modbus TCP protocol, MQTT protocol, which is able to connect to cloud platform for real time monitoring. 

The remote control and alarm module is able to perform certain actions automatically at a preset time, which can effectively reduce human participation and greatly improve efficiency. For example, turn on the water pump regularly, discharge sewage regularly, start the exhaust fan regularly, switch equipment on and off at regular intervals, and so on.
