Product Description
The Yokogawa SSC60D-S2522 is a high-availability duplexed Safety Control Unit (SCU) designed for the ProSafe-RS safety instrumented system (SIS). This rack-mountable unit serves as the core processor for emergency shutdown (ESD) and fire & gas (F&G) systems, executing critical safety logic with deterministic speed via the Vnet/IP network.
The duplexed architecture features two independent processor modules running in parallel, ensuring that a single hardware failure does not compromise safety functions. This configuration includes dual-redundant power supplies and is treated with ISA Standard G3 conformal coating, providing enhanced protection against corrosive gases in industrial environments.

Application Scenarios
The SSC60D-S2522 is ideal for mission-critical safety loops in:
-
Oil refineries
-
Offshore platforms
-
Chemical processing facilities
It monitors field inputs and executes safety actions (e.g., closing isolation valves) to prevent hazardous events, ensuring both personnel safety and environmental protection in high-risk industrial zones.
FAQ
Q: What does “Duplexed” mean for the SSC60D?
It means the unit contains two processor modules operating in synchronization. If the primary processor fails, the secondary processor takes over instantly without interrupting safety logic execution.
Q: Why does this model come without a Safety Control Function License?
The SSC60D-S2522 is typically supplied as a hardware-only unit for maintenance or replacement purposes. The functional software license is managed at the system level or purchased separately depending on the project’s software revision (R4.01 or later).
