Cellular M2M IoT RTU S270 is wireless internet of things device, 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. 

Cellular M2M IoT RTU S270 provides 2 digital inputs, 2 analog or PT100 Resistance Temperature Detector (RTD) inputs, 2 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.

Cellular M2M IoT RTU S270 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, MQTT Protocol too. This is very useful if you need remote control onsite devices with low cost solution.

Cellular M2M IoT RTU S270 is design for working in the harsh industrial application environment, widely used in a variety of industrial automation, security monitoring system, automatically measurement and control system, BTS monitoring, remote data acquisition, telemetrically systems, automatically control system. It can be used as a remote switch, remote I/O, remote smart PLC, timer switches.

Cellular M2M IoT RTU S270 can be used as remote access control for BTS monitoring, the authorized users can open the gate or turn on the machine with a free charge call at specified time, this is useful for daily maintenance to save the time of traditional authorized.

Cellular M2M IoT RTU S270 performs as Modbus TCP Slave over GPRS/3G/4G network.
