Function and Positioning

This module is a critical electromechanical communication expansion component for B&R industrial control systems, dedicated to serial data interconnection between main controllers and electromechanical equipment. It supports point‑to‑point and multi‑drop network topologies via RS232 and dual RS485/RS422 ports, enabling seamless connection with electromechanical devices such as motor drives, sensors, actuators, HMIs, and third‑party controllers. Independent galvanic isolation per channel eliminates cross‑interference and common‑mode voltage risks caused by electromechanical operation, ensuring stable communication in noisy industrial sites. It reduces the main CPU’s communication burden, improves system networking flexibility, and serves as a bridge for electromechanical system integration and data transmission.
