Ethernet Gateway Interface

NWJ-804Application Scope

Primarily used in substation automation systems of various voltage levels to perform protocol conversion between protection or measurement and control devices and the backend system.

Hardware Configuration

• Rich interfaces: Provides 2 RS-485 interfaces, 2-4 10M/100M Ethernet interfaces, and a ConSOLE debugging port.
• Power specifications: Single power supply, supports AC/DC 220V input.
• Dimensions: Compact size of 280mm x 160mm x 34mm, easy to install.

Functional Features

• Powerful protocol conversion: The device can run multiple protocol conversion services simultaneously, converting protocols such as IEC103 into IEC61850 protocol data.
• Supports multiple functions: The standard version supports GOOSE logic lock function, simplified COMTRADE format, and automatic generation of binary fault recordings.
• Excellent network performance: Supports star or ring network topologies; network redundancy mode only supports dual-network dual-IP mode, not dual-network single-IP mode.
• Comprehensive remote functions: Provides telnet remote login and FTP upload/download capabilities.

Technical Parameters

• Serial communication: Baud rate configurable from 4800bps to 38400bps, default 9600bps; terminal wiring with 2000V DC isolation protection.
• Ethernet performance: Network speed 10M/100M, RJ-45 interface, recommended cable length within 80m.
• Low power consumption: Power consumption 20W.
