Yaskawa SI-485/J RS-485 MEMOBUS/Modbus communication interface option for compatible J1000 AC drives, enabling PLC communication, drive operation, monitoring and parameter setting over a serial network.
£36.80
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.
Communication options such as the Yaskawa SI-485/J allow compatible inverter drives to be integrated into wider automation systems. Through RS-485 MEMOBUS/Modbus communication, users can start and stop the drive, change speed references, monitor operating data and adjust parameters from a connected controller.
This makes the SI-485/J useful for machine builders, panel builders and maintenance teams who need centralised control of multiple drives. Its compact design and direct installation help simplify J1000 drive networking in industrial motor control applications.
