Product Description

The SSC60D-S2121 is a high-performance duplexed safety control unit designed for the Yokogawa ProSafe-RS platform. This unit functions as the primary logic solver for safety-critical protection loops, delivering SIL3-certified safety processing in accordance with IEC 61508 functional safety standards.

The SSC60D-S2121 utilizes a duplexed redundant processor architecture, ensuring continuous safety operation even in the event of a single processor failure. If a fault occurs, the secondary processor maintains uninterrupted logic execution, preventing nuisance trips while preserving plant and personnel safety.

As a core component of Emergency Shutdown (ESD) and Fire & Gas (F&G) systems, the module provides:

• High-speed deterministic safety logic execution

• Redundant safety processing pathways

• High-density safety network communication

• Robust diagnostic self-checking mechanisms

The module is optimized for integration with modern safety control networks using Vnet/IP communication and can operate within high-reliability industrial environments such as petrochemical and energy processing facilities.

Technical Specifications

Industrial Application

The SSC60D-S2121 is widely used in high-risk industrial sectors, including:

• Petrochemical refineries

• Offshore oil and gas platforms

• Power generation plants

• Chemical processing facilities

It acts as the primary safety logic engine for managing interlocks and automatically driving process equipment to a safe state during abnormal operating conditions.

Technical FAQ

What is the difference between SSC60D-S2121 and SSC50D models?
The SSC60D-S2121 provides enhanced processing performance, expanded memory capacity, and higher data throughput to support more complex safety logic programs in modern safety architectures.

Can the SSC60D-S2121 integrate with CENTUM VP?
Yes. The module can integrate with Yokogawa CENTUM VP via Vnet/IP networking, allowing centralized monitoring and control while maintaining strict separation between safety and process control layers.
