Product Introduction
The Yokogawa CP451 is a core high-performance processor module engineered specifically for Yokogawa’s industry-leading CENTUM CS 3000 and CENTUM VP Distributed Control Systems (DCS). Operating at the heart of the Field Control Unit (FCU), the CP451 executes complex control strategies, handles high-speed data acquisition, manages sequence control logic, and coordinates communication across the control network.
Designed for mission-critical continuous process industries—such as oil and gas refining, chemical manufacturing, power generation, and water treatment—the CP451 architecture supports dual-redundant configurations (“, active/standby pairing) to ensure uninterrupted plant availability and zero single-point-of-failure vulnerability.

Compliance & Standards Alignment
- Manufactured in accordance with rigorous Yokogawa quality control guidelines and international industrial automation standards.
- Conforms to heavy electromagnetic compatibility (EMC), CE, CSA, and hazardous location non-incendive ratings when housed in approved cabinet environments.
Technical Note: When deploying the CP451 in a dual-redundant controller setup, both modules must share identical hardware revision codes and compatible software build versions to ensure seamless bumpless transfer during active/standby failover sequences.
Storage & Asset Preservation Guidelines
- Store the processor card inside its original factory ESD-shielded antistatic packaging to protect static-sensitive CMOS microprocessors and memory controllers.
- Keep the storage facility clean, dry, and climate-controlled, maintaining relative humidity below 85% (non-condensing).
- Avoid physical mechanical shock, drops, or applying pressure to the edge-connector pins and front-panel diagnostic indicators.
Physical Installation Prerequisites
- Ensure that the target Field Control Unit (FCU) power supply rack and node sub-racks are completely isolated, de-energized, and locked out (LOTO) prior to inserting or extracting the processor module (unless executing an approved live replacement on non-critical redundant nodes).
- Observe strict electrostatic discharge (ESD) safety controls, including the mandatory use of a tested grounded wrist strap.
- Guide the module carefully along the enclosure slot tracks and press firmly to seat the backplane connectors before engaging retention mechanisms.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this Yokogawa processor module?
A: Distributed control system processor cards, industrial computer modules, and automation hardware typically classify under HS code 8538.90 (Parts suitable for use with electrical control apparatus) or 8537.10. Confirm exact classifications with your customs broker.
Q: Is the CP451 compatible with both CENTUM CS 3000 and CENTUM VP systems?
A: Yes, specific iterations and style revisions of the CP451 family are designed to bridge legacy CS 3000 upgrades or operate within modern CENTUM VP environments, depending on the exact suffix code (e.g., CP451-10 vs CP451-50).
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market availability, global supply chain tiers, and factory-new vs. surplus condition status; contact our technical sales desk for a formal, time-sensitive quotation.
