Model: S251

Name: Cellular Single Phase Electric Measuring RTU

The Cellular(GSM/GPRS/3G/4G/NB-IoT) Single Phase Electric Measuring RTU is special designed for remote monitoring and measuring the single phase voltage, current, active power, re-active power, apparent power, power factor, frequency, active power, reactive power, active energy, re-active energy. If any item exceeds the pre-set value, then it will alert by SMS, Voice call, Cloud, APP, Wechat, Web Server, SCADA, HMI, DSC immediately.

The Cellular Single Phase Electric Measuring RTU is an industrial class, high reliability, high stability, and programmable Remote Terminal Unit (RTU).  It embedded 32-Bit High Performance Microprocessor MCU, integrated special measurement chip and inbuilt industrial Cellular module. It provides 4 digital inputs, 2 relay outputs, 1 ambient sensor input for monitoring onsite temperature and humidity.

The Cellular Single Phase Electric Measuring RTU can monitoring and operates the I/O ports by SMS, APP, Web Server, internet, timers and programmed inter-lock events automatically.

The Cellular Single Phase Electric Measuring RTU inbuilt TCP/IP protocol stack over cellular network or Ethernet to make it suitable for internet of things (IoT) applications, 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.
