 1. Product Overview

The ABB SDCS-PIR-21 Buffer Board is a key signal buffering and relay module for industrial automation, robot control systems, and drive modules. It stabilizes, isolates, and extends signals to ensure integrity and reliability during long-distance transmission or multi-module connections of high-speed pulse, analog, or digital signals. The SDCS-PIR-21 supports multiple input/output types, with industrial-grade interference resistance, making it an essential component in ABB automation modular systems.
