YOKOGAWA CP451-51 Multifunction Processor Module

Procurement Guidance

  1. Compatibility Notes
    • Valid for CENTUM CS3000/VPS and AFV300/AFV400 systems; replaces legacy CP451-11 (#ref_11).
    • Suffix -51 denotes standard non-explosion-proof variant; confirm ISA G3 compliance for corrosive environments (#ref_11).
  2. Critical Accessories
    • Backplane Adapter (e.g., Yokogawa SDCS-PIN-24) for DCS rack integration (#ref_5).
    • Battery Backup Module (IC698ACC701) for RAM retention during power loss (#ref_8).
  3. Avoid Mismatches
    • Standalone HART isolators → Use Yokogawa CP451-HART.
    • Low-power I/O modules → Refer to Yokogawa AFL111.
  4. Authenticity Verification
    • Holographic seals on factory-sealed units; 12-month warranty (#ref_3).
    • Cross-check part number 3BHE030579R0003 for industrial-grade variants (#ref_14).
