Yokogawa CP471-00 Processor Module Centum VP Basic Type Without Explosion Protection
Product Overview
The YOKOGAWA CP471-00 is the core 32-bit real-time processor module for CENTUM VP and CENTUM CS 3000 distributed control systems. Operating at 100 MHz with 64 MB SDRAM, it handles up to 8,000 I/O points, 500 control loops, and 100 ms scan tasks. Hot-swap capability, built-in diagnostics, and SIL 2 certification make the CP471-00 ideal for continuous process plants, power generation, and offshore platforms.
Key Features & Benefits
• 32-bit RISC CPU @ 100 MHz – deterministic control loops
• 64 MB SDRAM & 8 MB flash – large application memory
• Up to 8,000 I/O points – scales from skid to plant-wide
• Redundant CPU ready – seamless switch-over < 50 ms
• Hot-swap module – replace without rack power-down
• Built-in self-diagnostics – CPU, memory & bus health LEDs
• SIL 2 certified (IEC 61508) – safety-critical processes
• 1× ESB bus interface – 100 m remote I/O extension
• Supports CENTUM VP R6 or later – future-proof upgrade path
