Name: GPRS Modbus RTU

Model: S280(4AIN, 2DIN,2DOUT)

The GPRS Modbus RTU S280 embedded with High reliable ARM9 MCU and industrial GPRS Engine inside. It is not only a GPRS RTU (Remote Terminal Unit), but also a GPRS DTU (Data Transfer Unit) and a GPRS Data Logger. It is the best solution for small application data logging

and remote monitoring.

The GPRS RTU S280 supports 4AIN, 2DIN,2DOUT IO port monitoring by Modbus TCP Protocol over GPRS. It can be connected to various transducers like pressure transducer, oil level transducer, current transducer, voltage transducer, temperature transducer and so on. Also it can be connected to digital detectors and digital outputs.

The GPRS RTU S280 supports transparent and non-transparent data transfer by RS485 and RS232

over GPRS. It can be connected to intelligent instrument and industrial meters directly to read the values of analog input, TTL, digital input, pulse counter and so on.

The GPRS wireless communication has become widely used of industrials and utilities and many customers are requiring reliable, flexible and cost-effective data channel to build their information system. Many applications such as Remote device monitoring, remote read meters, ATM, data logging system, POS, SCADA and surveillance system will require data channels covered all country.

GPRS RTU S280 is an ideal solution for factory automation, environmental monitoring and remote device management for M2M industry. Meanwhile, it is supplied with simple and user friendly PC Configurator to configuration, easy to installation.
