CWT5111 GPRS fuel level sensor data logger, GPRS data logger, GPRS RTU
Supports 3G version ( skype: glare.wang)
CWT5111 GPRS Data logger accurately measure and record data from fuel level sensors or meters with 4-20mA or 0-5V analogue output, then transmite the data to GPRS server. Users can monitoiring the data online
With 1 RS-232 serial port, 8 Digital Inputs, 8 drivable Outputs, 4 analog inputs, CWT5111 is an ideal solution for factory automation, environmental monitoring and remote device management for M2M industry.
GPRS feature
Support connects 4 servers, the servers must connect internet and have static public IP address or Dynamic Domain name
GPRS Transmission base on TCP/IP
Support modbus TCP protocol or CWT_IO protocol
