CWT5018 GPRS Ethernet Modbus data logger

Support 3G version ( skype: glare.wang)

The CWT5018 GPRS Enthernet Modbus Data Logger is used for recording data in a line Modbus.

The data logger is operating in stand-alone , can be connected to Master Modbus , or in the Modbus Slave , via a RS485 or RS232.

The data acquired from the device can be transmit to web server by GPRS and Ethernet .
