Remote Terminal Unit(RTU)
  • Data acquisition, transmission and intelligent control over IoT devices

  • Support a range of cellular networks like GSM, WCDMA and LTE 4G

  • High reliability, cloud-based, high-performance embedded processor

RTU S3A23 transmission unit, is a type of industrial-grade remote wireless data transmission equipment, supporting 4G LTE, 3G and 2G wireless network. These wireless protocols include GPRS/WCDMA/TDSCDMA/LTE-FDD/LTE-TDD.

RTU adopts industrial-grade ARM processor, real-time operating system as its software platform. With high capacity RAM and embedded MQTT protocol, online maintenance technology, Synway's RTU assures the data terminal online, smooth data transmission and achieve high-speed and reliable data transmission.

The cloud management platform is the software management platform for monitoring and operating S3A23 devices. Synway RTU S3A23 is connected to the cloud administration platform via the MQTT interface and reports the data to center. The platform helps to acquire real-time device data, store it to the database, and synchronize among users. The cloud platform can obtain and send the configuration data of the device on remote.
