YOKOGAWA SDV144‑S63‑ 16‑Channel SIL‑Certified Digital Input Module

2. Product Overview

SDV144‑S63 is a 16‑channel digital input module for Yokogawa ProSafe‑RS safety instrumented system (SIS). It receives dry‑contact binary status signals from field limit switches, safety interlock sensors and relay contacts. Each channel provides optical‑galvanic isolation between field circuit and safety backplane, achieving high‑level noise immunity. Compliant with SIL2 safety integrity requirements, supports hot‑swap operation for online rack maintenance without system shutdown. LED per‑channel status indicators support fast on‑site fault diagnosis. It is critical spare for petrochemical and power‑plant safety shutdown control racks.
