CWT5002-2 MODBUS GPRS RTU 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.
With 8 Digital Inputs, 8 drivable Outputs, 4 analog inputs and 1 selectable RS-232/485 serial port connect slave to read and writer 32 registers, CWT5002-1 is an ideal solution for factory automation, environmental monitoring and remote device management for M2M industry.
