The Yokogawa SSC60D is a Safety System Controller (SIS CPU module) used in Yokogawa ProSafe-RS (Safety Instrumented System).
It represents a higher-capacity / newer-generation safety controller class compared with earlier SSC10 series, and is used for larger or more complex safety applications.
Typical functions include:
- Emergency Shutdown System (ESD)
- Fire & Gas System (F&G)
- Burner Management System (BMS)
- High-integrity process interlocks
- Complex multi-node safety logic processing

System Role
The SSC60D acts as the high-performance safety logic engine:
Field Inputs → Input Modules → SSC60D (advanced logic processing) → Output Modules → Final shutdown devices
It provides:
- High-speed safety logic execution
- Large-scale interlock handling
- Multi-node safety coordination
- Redundant synchronization between CPU pairs
- Continuous system diagnostics and fault detection
