Mitsubishi ERNT-AQB65N Bus Connection Unit for Melsec-Q Series

The Mitsubishi ERNT-AQB65N (ERNT-AQB65N) is a dedicated bus connection unit engineered for Mitsubishi Electric Melsec-Q series programmable logic controller systems. Serving as a specialized interface component, this module provides two communication ports or channels to connect the Q central processing unit with extension lines and compatible industrial interface equipment. The unit is functionally equivalent to the GT15QBUS2 bus connection interface, ensuring direct compatibility and simplified integration in systems requiring dependable CPU bus communication. Designed for integration within standard Melsec-Q system architectures, the module facilitates reliable signal transfer and multi-drop communication between the main controller and connected peripheral units. The dual-port layout enables seamless connectivity for distributed equipment and display networks without sacrificing processing speed or operational stability. The Mitsubishi ERNT-AQB65N is commonly deployed across automated production lines, process machinery, and industrial plants where stable high-speed bus connectivity is required for Melsec-Q controllers.
