PSCCM22AAN 16418-5314 is a core Critical Control Module (CCM) of the Yokogawa ProSafe-PLC Safety Control System, with the material code 16418-5314. Designed specifically to meet the critical control requirements of Safety Instrumented Systems (SIS) in industrial processes, it features a high safety integrity level compliant with the IEC 61508 standard and a redundant architecture. The module can stably execute safety logic such as Emergency Shutdown (ESD) and Fire & Gas Detection (FGS/GDS), and is suitable for harsh industrial scenarios including petrochemicals, electric power, and metallurgy. It provides reliable control assurance for personnel, equipment, and environmental safety in process industries, while being compatible with mainstream industrial communication protocols to enable seamless integration into existing automation systems and support flexible expansion.
Hardware Configuration and Performance Parameters
Processor and Storage: Equipped with a 32-bit high-performance RISC processor, it ensures fast computation and real-time response for complex control algorithms. The module comes with standard 8MB RAM for data caching and 2MB Flash for program and parameter storage, supporting online program modification and parameter updating. Configuration adjustments can be completed without system shutdown.
Power Supply and Redundancy: Adopting 24VDC industrial standard power supply, it is integrated with overvoltage, overcurrent and reverse connection protection functions. It supports dual-power redundant input and module-level hot redundancy configuration, with redundancy switching time less than 200ms, ensuring uninterrupted system operation in case of power supply interruption or module failure.
Communication Interfaces: It supports multiple communication interfaces including Ethernet and RS-232/485, and is compatible with mainstream industrial protocols such as Modbus and Profinet. Bidirectional data interaction can be achieved with DCS systems, HMIs, field instruments and upper monitoring devices. Meanwhile, it supports secure communication protocols to prevent data tampering and interference during transmission.
Environmental Adaptability: The operating temperature range is -20°C to +70°C, with relative humidity of 5% - 95% (non-condensing). The module itself has an IP20 protection rating, suitable for harsh industrial field conditions with dust, vibration and electromagnetic interference, and complies with industrial-grade shock and vibration resistance standards.
Physical Specifications: Featuring a standard 3U rack-mount design, it has dimensions of approximately 120mm×80mm×50mm and a weight of around 300g. It is compatible with the standard racks of the Yokogawa ProSafe-PLC system and supports hot swapping, facilitating on-site installation and maintenance.
Key Functional Features
Safety Logic Execution: It supports safety-oriented programming methods including Ladder Diagram (LD) and Function Block Diagram (FBD), enabling the implementation of complex safety interlock logic such as process parameter overlimit protection, equipment interlock control, and emergency shutdown sequence execution. The control loop response time is less than 10ms, meeting the requirements for high-speed safety control.
Flexible Expansion Capability: It is compatible for combined operation with critical analog modules like PSCCAMAAN, digital I/O modules and communication expansion modules, supporting up to 32 expandable I/O modules to adapt to safety control systems of varying scales. Modules communicate via a high-speed backplane bus with a data transmission rate of 100Mbps, ensuring real-time signal synchronization.
Convenient Maintenance and Diagnostics: It provides comprehensive self-diagnostic information, allowing users to check module operating status, fault codes, historical events and other data via host computer software. It supports remote diagnostics and firmware upgrades, and is equipped with a watchdog timer function to prevent system out-of-control caused by program infinite loops, improving system operation and maintenance efficiency.
Application Scenarios
PSCCM22AAN 16418-5314 is widely applied in process industrial fields with stringent safety requirements, including the Emergency Shutdown (ESD) systems of catalytic cracking units and hydrogenation units in the petrochemical industry; the Burner Management Systems (BMS) in the power industry; the blast furnace gas safety monitoring systems in the metallurgical industry; as well as the safety control of hazardous chemical storage and reaction processes in the chemical and pharmaceutical industries. It effectively prevents safety accidents caused by process abnormalities and equipment failures, ensuring the stability and safety of production processes.
