Product Description: 7EX470.50-1

1. Product Overview

The 7EX470.50-1 is a 2003-series CAN bus controller from B&R Automation, designed as a high-performance communication module for distributed industrial control systems. It provides two electrically isolated CAN interfaces and a integrated 24 VDC power supply (14.5 W), enabling reliable, real-time data exchange between B&R 2003-series PLCs, I/O modules, and third-party CANopen/CAN2.0A/B devices. The screw-in form factor ensures seamless integration with B&R 2003 backplanes and CPUs (e.g., 7CP476-020.9).
