1. Product Title

Yokogawa SDV144‑S13‑ 16‑Channel Isolated Digital Input Module for ProSafe‑RS SIS

2. Product Overview

SDV144‑S13 is safety‑grade digital input module for Yokogawa ProSafe‑RS safety instrumented system (SIS). It acquires 24 VDC dry‑contact and proximity‑switch status signals from field safety devices including emergency stop buttons, fire‑gas detectors and interlock switches. Module‑wide galvanic isolation protects safety logic from field‑side electrical interference. Integrated circuit‑monitoring diagnostics detect wire open‑circuit and short‑circuit faults. Supports dual‑redundant configuration and achieves SIL3 safety integrity level under redundant setup. Hot‑swap capable for on‑line maintenance. SDV144‑S13 is critical spare component for ESD and F&G safety‑system cabinet maintenance and commissioning work.
