The GSM 3G 4G M2M RTU is an industrial class, high reliability, high stability, and programmable Remote Terminal Unit (RTU).
It embedded 32-Bit High Performance Microprocessor MCU, inbuilt industrial Cellular module. It provides 4 digital inputs,
4 analog or PT100 Resistance Temperature Detector (RTD) inputs, 4 relay outputs, 1 ambient sensor input for monitoring
onsite temperature and humidity. It can monitoring and operates the I/O ports by SMS, APP, Web Server, internet, timers and
programmed inter-lock events automatically.
The GSM 3G 4G M2M RTU 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.
