Présentation du produit
The Yokogawa SSC10D-S2111 Duplexed Safety Control Unité is a high-integrity, fault-tolerant safety controller developed for use in Yokogawa’s ProSafe-RS Safety Instrumented System (SIS). Designed to meet the most stringent safety and reliability standards, the SSC10D-S2111 is responsible for executing safety logic, managing redundant safety I/O operations, and ensuring continuous plant operation even in the event sur hardware or communication faults.
This controller integrates seamlessly with CENTUM VP and other Yokogawa distributed control systems, forming a unified architecture for both process control and safety management. It employs a dual-redundant architecture, where two processors operate in parallel to continuously cross-check logic execution, guaranteeing safe operation even if one processor fails.
The SSC10D-S2111 provides superior diagnostics, self-checking mechanisms, and deterministic performance. It is widely used in industries where process safety, reliability, and availability are paramount — including oil & gas, petrochemical, power generation, and refining sectors.
