B&R X20SI9100 Serial Interface Module RS485/RS422 PLC Communication For SCADA Systems | T??V-Certified

Description

The B&R X20SI9100 is a TUV-certified serial interface communication module designed for integration with PLC systems and SCADA (Supervisory Control and Data Acquisition) systems in industrial automation environments. As a specialized PLC communication module, it supports RS485/RS422 serial communication protocols, enabling reliable data transmission between PLCs and other industrial devices, sensors, or control systems.

Drawing on standard RS485/RS422 capabilities, this module features differential signal transmission, delivering strong anti-interference performance and extended communication distances compared to older protocols like RS232. Proper installation requires consideration of terminal resistors to suppress signal reflection and ensure data transmission reliability, with resistor values and placement tailored to bus length.

As part of a PLC system’s communication infrastructure, it facilitates seamless data exchange for industrial control and data collection tasks, supporting core SCADA functions such as remote monitoring, data aggregation, and device control. Like other B&R X20 series modules, it is engineered for rugged industrial use, with TUV certification confirming compliance with strict industrial safety and performance standards.
