It is responsible for executing critical safety logic to protect personnel, assets, and the environment in hazardous industrial processes. Designed to meet SIL3 requirements in a single-module configuration, it handles Emergency Shutdown (ESD) and Fire \u0026amp; Gas (F\u0026amp;G) applications with high reliability and deterministic performance. The module integrates with Yokogawa CENTUM VP via Vnet\/IP, enabling coordinated monitoring of safety functions while maintaining strict separation between control and safety layers. We supply this unit as 100% brand new, original factory hardware to ensure maximum integrity and compliance with safety system requirements.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel Number\u003c\/td\u003e\n\u003ctd\u003ePSCCM24AAN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eCCM (Critical Control Module)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e4.0 cm × 26.0 cm × 30.6 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.96 kg \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProcessor Architecture\u003c\/td\u003e\n\u003ctd\u003eDual-microprocessor with hardware diagnostic pairing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eVnet\/IP safety communication support\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003e100% Brand New Original\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003ch3\u003eEngineering Advantages\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIntrinsic SIL3 Safety Logic\u003c\/strong\u003e\u003cbr\u003eThe PSCCM24AAN employs a “Pair \u0026amp; Spare” dual-processor architecture that continuously cross-checks all executed logic. Any discrepancy between processors triggers an immediate transition to a safe state, ensuring deterministic and fail-safe operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh-Density Safety Processing\u003c\/strong\u003e\u003cbr\u003eWith advanced processing capability, the module can manage large numbers of safety I\/O points within a single controller.
