CWT5002-1 MODBUS GPRS RTU enables various kinds of devices with I/O and Standard MODBUS protocols to communicate over GSM/GPRS network and the Internet easily and freely. It can construct a smooth “GPRS Data Tunnel” between Host End and Remote End, ensuring an efficient communication for data transmission and remote device management. It also support send user-defined alarm sms when pre-defined alarm condition happens, and can be controlled via SMS command.

With 4 Digital Inputs and 4 drivable Outputs, 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.
