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).
