Product Introduction

The Yokogawa SSC60D is a high-integrity Safety Control Unit designed to perform safety instrumented functions (SIFs) in compliance with IEC 61508/61511 SIL3 standards. As a part of Yokogawa’s ProSafe-RS safety instrumented system (SIS), the SSC60D plays a critical role in achieving safe and reliable plant operations in industries such as oil & gas, petrochemicals, and power generation.

The SSC60D is built for dual-redundant or simplex configurations, offering real-time diagnostics, safe-state actions, and robust fail-safe features. The unit handles safety I/O processing, logic execution, and communication with the Safety Engineering Station (SENG) via Vnet/IP, ensuring deterministic and secure data transmission.

Engineered with Yokogawa’s reputation for reliability, the SSC60D ensures compliance, flexibility, and lifecycle support, making it a cornerstone in high-performance safety system deployments.

Product Applications

The Yokogawa SSC60D is utilized in safety-critical applications that require fail-safe operation and certified protection layers. These applications include:

• Emergency Shutdown Systems (ESD)
  Triggers plant-wide or section-specific shutdowns upon detection of unsafe conditions.

• Burner Management Systems (BMS)
  Ensures controlled start-up and safe shutdown of burners in combustion systems.

• Fire and Gas Systems (F&G)
  Monitors toxic gas levels, fire detection points, and initiates alarms or shutdowns.

• High-Integrity Pressure Protection Systems (HIPPS)
  Provides overpressure protection for pipelines and pressure vessels.

• Turbine Protection Systems
  Offers automated responses to overspeed, vibration, and lubrication system failures.

• Critical Process Control in Hazardous Areas
  Assures reliability and safety in ATEX/IECEx environments.

The SSC60D’s integration with DCS platforms like CENTUM VP enhances visibility and operational control from a unified engineering environment.
