Product Description

The Yokogawa SSC10S-S2121 S1 functions as the core processing engine of the ProSafe-RS Safety Instrumented System (SIS). Designed for SIL 3 compliant applications, this rack-mount controller adopts a dual-redundant architecture to eliminate single points of failure.

With parallel processor synchronization, redundant communication buses, and integrated power redundancy, the unit ensures uninterrupted execution of safety logic during maintenance or hardware faults. It is optimized for mission-critical shutdown and fire & gas (F&G) systems.

Core Processing & Memory

Operational Overview

The SSC10S-S2121 S1 integrates:

• Dual-redundant power supply architecture

• Redundant communication buses (V net & ESB)

• High-speed deterministic safety logic execution

• Compact chassis design for rack-mounted installations

This architecture ensures continuous safety function execution in high-risk industries such as oil & gas, petrochemical, power generation, and chemical processing.

Application

• Emergency Shutdown (ESD) systems

• Fire & Gas (F&G) detection systems

• High-integrity SIL 3 safety loops

• Integrated process safety management within ProSafe-RS

FAQ

Q: How does the “S2” suffix affect the power configuration?
A: The SSC10S-S2121 S1 supports flexible power input (AC or DC) depending on the installed power supply modules, allowing site-specific electrical integration.
