GW1118-8DI(RS-485) - Modbus RTU / ASCII gateway to Modbus TCP, 8 serial ports RS-485/422 and 2 Ethernet ports

Industrial Modbus RTU / ASCII gateway to Modbus TCP. 8 serial ports RS-485/422 and 2 Ethernet ports, wide temperature range, metal housing with IP30 protection.

GW1108-8DI(RS-485) is an Ethernet Modbus gateway that converts between Modbus TCP and Modbus RTU/ASCII protocols. It provides 8 port RS-485/422 serial and 2 10/100M Ethernet ports. Modbus TCP, Modbus RTU and Modbus ASCII protocol are integrated in the products, users can easily realize the seamless integration of Modbus Ethernet devices and Modbus serial devices and even multi master and slave hybrid networks. At the same time, the user can be set up by Web or Telnet. The simple design can not only realize the fast application, but also guarantee the application of the entire real industrial environment. The products using EMC protection design, can work in rugged environment.
