RS-IGP is an industrial gateway designed with centralized integration, supporting 1 Ethernet port and 2 or 4 isolated RS485 serial ports, capable of converting between different protocols. The module is enclosed in an aluminum shell, and the circuit design has strong resistance to electromagnetic interference, making it particularly suitable for communication conversion fields such as energy management and production data acquisition. RS-IGP can support multiple protocols. Rich communication interfaces, different interfaces can simultaneously use different protocols for communication. RS-IGP is economical and practical, and its programmable features are different from other customized gateways. It can program and define data and protocols.
