The RTU exists in the remote meter reading system as a communication relay station between the water meter and the management system terminal. They are powerful, exquisite in appearance, stable and reliable, free of commissioning and maintenance.
The network is connected to the background data center through NB-IOT to realize the function of data acquisition.
The RTU adopts high-performance industrial-grade 32-bit processor and industrial-grade wireless module, with embedded real-time operating system as the software support platform, and provides RS232 and RS485 interfaces at the same time, which can realize analog signal acquisition, value conversion and digital signal acquisition etc.. It can be easily to operate by the provided cloud, app, and web server, or integrated to you IoT applications according to the TCP/UDP protocol, or integrated to SCADA systems by standard Modbus TCP protocol, too. This is very useful if you need remote control onsite devices with low cost solution.
The RTU has excellent electromagnetic compatibility performance, can resist the high voltage peak pulse, strong magnetic field, strong static electricity, lightning and wave interference, and has a strong temperature adaptive function.
