Product Description
The SDV144-S13/D4A00 (SDV144) is a high-integrity 16-channel digital input module designed for Yokogawa ProSafe-RS Safety Instrumented Systems (SIS). It is purpose-built to monitor safety-critical field signals—including Emergency Shutdown (ESD) buttons, fire and gas detectors, and process interlocks—ensuring compliance with strict Safety Integrity Level (SIL) standards.
This S13 version is hardened for harsh industrial environments, featuring ISA Standard G3 corrosive gas resistance. The D4A00 option equips the module with a KS Cable Interface Adapter, allowing secure, high-density connections to terminal boards using multi-pin cables. This ensures wiring integrity and operational reliability, which is critical for high-SIL safety loops.

Application Scenarios
The SDV144-S13/D4A00 is widely used in oil & gas, petrochemical, and offshore platforms for capturing signals that trigger emergency shutdowns and safety interlocks. Its G3 corrosive gas protection ensures reliable operation even in harsh atmospheres with hydrogen sulfide (H₂S) or chlorine, providing a fail-safe path to protect personnel and equipment.
Technical FAQ
What is the difference between SDV144 and ADV151?
The SDV144 is a safety-certified SIS module with higher isolation, diagnostic self-tests, and SIL-rated performance. The ADV151 is a standard control module for CENTUM VP DCS and is not suitable for high-SIL safety loops.
Why use the D4A00 interface?
The D4A00 adapter provides a standardized multi-pin KS cable connection, reducing manual wiring time and minimizing the risk of wiring errors—critical for commissioning and maintaining safety-instrumented systems.
