SI-485/J Ser. Comm. Interf. RS485

Why Choose the Yaskawa SI-485/J RS-485 MEMOBUS/Modbus Interface?

The Yaskawa SI-485/J is a dedicated RS-485 MEMOBUS/Modbus communication interface option designed for compatible Yaskawa J1000 AC drives. This compact option module enables the drive to communicate with PLCs, HMIs and other automation control devices over a serial network.

By adding RS-485 communication to the J1000 inverter, the SI-485/J allows users to operate the drive, monitor operating status and change parameter settings remotely. It is ideal for industrial automation systems where reliable serial communication and centralised drive control are required.

The SI-485/J installs directly onto the compatible drive and provides a dedicated interface for MEMOBUS/Modbus communication. It supports multi-drop network integration, making it suitable for systems with multiple inverter drives connected to a single controller.
