S272 GSM/3G/4G M2M RTU - Controller

The GSM S272 3G/4G M2M RTU is an industrial-class controller, with high reliability and stability and the possibility of using a programmable remote terminal (RTU). It has an integrated 32-Bit high-performance MCU microprocessor and a Cellularmodule. It provides 2/4/8 digital inputs, 2/4/6 analog inputs or PT100 temperature resistance detector (RTD) input, 2/4 output relays, 1 input for an environmental sensor that monitors room temperature and humidity along with an RS485 serial port. It has the ability to monitor and perform operations on the I/O port via SMS, APP, Web Server, Internet, timers and programmed inter-lock events automatically.

The built-in GSM 3G 4G M2M RUT TCP/IP protocol, makes it suitable for Internet of things (Iot) applications and can easily operate via Cloud, App and Web server or integrated by you Iot application according to TCP/UDP protocol or also with integrated SCADA systems via standard Modbus TCP protocol. This is very useful in case of remote use of devices with low cost.

GSM 3G 4G M2M RTU is designed for harsh industrial applications, widely used in the field of industrial automation and monitoring systems, providing automatic measurement and control systems, BTS monitoring, remote data reception, telemetric systems and automatic control system. It can be used as a remote switch, I/O, remote smart PLC and as a timer.

The GSM 3G 4G M2M RTU is also used as a control that remotely controls access to BTS monitoring, authorized users can open a gateway or open a machine with a free call at a certain time. Useful for daily maintenance and saves time from the traditional way of authorization.

The GSM 3G 4G M2M RTU S272 supports a clean data migration and Modbus Slave function via GPRS/3G/4G network and RS485 serial port. I/O directly from the application without having to spend money to deploy a Cloud + Web Server + APP again.
