The SDCS‑PIN‑51 (3BSE004940R1) is a measurement interface card designed for ABB drive control systems. It collects analog inputs from sensors (such as 4–20 mA or 0–10 V signals) and converts them into accurate data for the drive logic. It is key for precise motor control and stable process operation.
The module is built for industrial conditions, with robust components, electrical noise protection, and extended temperature tolerance. It improves measurement reliability and reduces load on the main control board.
