GSM 3G GSM 3G 4G SMS Remote Relay Switches (4 Relay Outputs)

Product Description

The GSM 3G 4G Remote Relay Switch is an industrial class, high reliability, high stability Remote Terminal Unit (RTU).  It embedded 32-Bit High Performance Microprocessor MCU, inbuilt industrial Cellular module, equipped 2 Solid Relay inside, can contact to electric device directly, special for remotely switch ON/OFF onsite devices by SMS, APP, Web Server, internet or timers automatically.

The GSM 3G 4G Remote Relay Switch inbuilt TCP/IP protocol stack 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.
