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.
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.
