B&R X20BT9400 Bus Transmitter Module

Product Description

The B&R X20BT9400 is an X2X Link Bus Transmitter Module designed for the B&R X20 I/O System. It is used to expand the X20 system by connecting X67 remote I/O modules through the X2X Link communication network, enabling flexible distributed I/O expansion in industrial automation applications.

The module also provides power supply for internal I/O modules and integrated X67 system power supply, allowing X67 modules to be connected without requiring a separate X67 power supply module.
