1. Product Title

Yokogawa SDV144‑S63‑ ProSafe‑RS 16‑Channel Isolated Digital Input Module

2. Product Overview

SDV144‑S63 is a SIL‑certified 16‑channel module‑isolated digital input module for Yokogawa ProSafe‑RS safety instrumented system (SIS). It accepts dry‑contact on‑off signals from field limit switches, safety interlock sensors and process trip devices, converting field contact status into internal safety‑bus data for SIS controller processing. Full module‑level galvanic isolation prevents fault propagation between field circuits and safety backplane. It supports dedicated Yokogawa‑style terminal cables, delivers maximum 40 ms input response time, and is designed for safety‑critical interlock, burner‑management and emergency‑shutdown applications in refineries, chemical plants and power stations.
