Product Code : GW1104-4DI(RS-485)
Brand Name : Mootek
Product Description
GW1104-4DI(RS-485) is an industrial Ethernet Modbus gateway that converts between Modbus TCP and Modbus RTU/ASCII protocols. It provides 4 port RS-485/422 serial (4 bit terminal block) and 1 port 10/100M Ethernet.
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. Power has over current, over voltage protection, and can work in rugged environment. The design supports 2 kinds of wall mounting installation, easy to use for your projects.
