Product Details

Brand Name	BLIIoT		Place of Origin	China
Model Number	S274

Product Description

The Industrial 4G Wireless Cellular RTU S274 features 4 digital inputs, 4 relay outputs, 1 temperature and humidity input, and 1 RS485 serial port. The RTU supports Modbus RTU over TCP, Modbus TCP, MQTT protocol.
The remote monitoring module is designed for remote measurement and control system and remote data acquisition telemetry systems, such as smoke, liquid, water, flow, flood, electricity, power, energy remote monitoring and remote control.

Inbuilt inter-lock logic programmer and powerful timer program function;
When alarm occurs, the RTU will notify users by SMS, dialing, and also uploading data to cloud platform, monitoring center. The RTU also can be used as a remote switch, remote I/O, remote smart PLC, timer switches.

The RTU supports BLIIoT IoT RTU protocol, Modbus RTU over TCP protocol, Modbus TCP protocol, MQTT protocol, which can communicate directly with the server, cloud platform or SCADA.
