Ethernet For Motor Drives

The SJ/L-EN communication module option provides the company's ac micro drives with an Ethernet interface.

Installed externally, the device connects to the network via a standard RJ45 connector. The module implements the Modbus/TCP protocol and incorporates seven LEDs to monitor board status and activity, an eight-position DIP switch for setting node address, and a Form-C alarm relay output.
