The SJ-EN Ethernet option board gives the SJ300 and L300P families of ac inverters a highperformance, easytouse Ethernet interface.
The board installs in an internal option-board expansion slot and connects to the network via a standard RJ45 connector. The SJ-EN implements the Modbus/TCP protocol for versatility and incorporates six LEDs to monitor board status and activity and an eight-position DIP switch for setting the node address.
