Product Description
The SSC10D-S2111 serves as the central processing core for the Yokogawa ProSafe-RS Safety Instrumented System (SIS). Engineered for SIL3 high-availability applications, this duplexed unit utilizes a redundant processor configuration to ensure that safety logic remains active even during hardware faults. It excels in managing complex safety loops, including Emergency Shutdown (ESD) and Fire and Gas (F&G) systems. The unit is designed for physical resilience, supporting wide-range thermal operating conditions and high-speed synchronization with external time references.

Application and Connectivity
The SSC10D-S2111 is typically deployed in large-scale refineries, chemical plants, and upstream offshore platforms. Its ability to interface with multiple safety nodes makes it ideal for distributed safety management. The inclusion of the IRIG-B interface is particularly beneficial for post-event analysis (Sequence of Events Recording), allowing for millisecond-accurate forensics.
Comparison: SSC10D vs. SSC10S
While the SSC10S is a single safety control unit intended for less critical loops, the SSC10D-S2111 features a duplexed architecture. This redundancy allows the unit to continue operating even if one CPU module fails, making it the preferred choice for processes where a "fail-to-safe" shutdown is not sufficient and operational continuity is required.
FAQ
Q: How do I handle maintenance on the memory backup battery?
A: The non-rechargeable battery within the SSC10D-S2111 is designed for a long service life, but it should be inspected during scheduled plant turnarounds. A low-battery alarm will be triggered in the ProSafe-RS maintenance console before the 3-year limit is reached.
Q: Is the cooling fan mandatory?
A: For standard indoor installations below 50°C, the unit is convection-cooled. The fan unit is only mandatory for cabinet environments where the temperature exceeds this threshold or where airflow is severely restricted.
