Yokogawa CP99A*A CENTUM VP Field Control Station Power Supply Module

Product Overview

The Yokogawa CP99A*A functions as the primary power supply module for Field Control Stations (FCS) within the CENTUM VP and CS 3000 Distributed Control Systems (DCS). This module converts incoming plant power into the stabilized, low-noise DC voltages required to operate the station’s CPU modules, I/O nests, and communication cards. It provides the foundation for system stability by ensuring consistent power delivery under varying load conditions. We supply this unit as 100% Brand New and Original, ensuring your control backbone remains powered by factory-certified hardware.

Part Number Breakdown

The CP99A*A utilizes Yokogawa's specific hardware coding to define its functional type:

Technical Specifications

The CP99A*A delivers high-efficiency power conversion with integrated diagnostic monitoring.

• Module Type: FCS Power Supply.

• System Compatibility: CENTUM VP / CENTUM CS 3000.

• Redundancy Support: Facilitates dual-redundant power configurations.

• Output Protection: Integrated overvoltage and overcurrent protection.

• Monitoring: Built-in status indicators (LEDs) for power-good and fault detection.

• Cooling: Convection cooled (design varies by FCS nest type).

• Condition: Guaranteed 100% Brand New and Original.

Engineering Advantages

The CP99A*A provides critical technical benefits for DCS infrastructure:

• Seamless Redundancy Integration: The module supports dual-power configurations within the FCS rack. In a redundant setup, if one CP99A*A unit encounters an input failure, the secondary unit takes over the full load instantly without causing a CPU reset or signal drop, ensuring 99.9999% system availability.

• Advanced Noise Filtering: Industrial environments suffer from significant electrical noise. The CP99A*A incorporates heavy-duty EMI/RFI filtering to prevent high-frequency interference from reaching the sensitive digital backplane, maintaining the integrity of high-speed control calculations.

• Continuous Health Diagnostics: The module communicates its status directly to the system's management software. This allows operators to receive real-time alerts regarding power degradation or voltage fluctuations before they lead to a system shutdown, enabling proactive rather than reactive maintenance.

• High Inrush Current Management: The internal circuitry manages the high inrush currents typical during system startups. This prevents nuisance tripping of upstream breakers and protects the downstream electronics from initial power surges during cabinet energization.

FAQs

• Can I replace a CP99A*A while the system is running?

  If your FCS is configured for power redundancy (dual modules), you can "hot-swap" a failed CP99A*A unit. The remaining module carries the load, allowing you to replace the faulty unit without interrupting the control process.

• Does this module handle both 110V and 220V AC inputs?

  Yokogawa power modules are often voltage-specific or auto-ranging depending on the specific assembly. Always verify the input voltage rating on the module’s nameplate or your system’s power distribution unit (PDU) before installation.

• How do I know if the module is failing?

  The front panel features status LEDs. A "Ready" or "Power" LED indicates normal operation, while a "Fault" or dark LED signals an issue. Additionally, the CENTUM VP HIS (Human Interface Station) will generate a system alarm for power supply abnormalities.

• Is this a brand new original part?

  Absolutely. We supply only 100% Brand New hardware. Every CP99A*A arrives in its original Yokogawa factory packaging with intact manufacturer seals and matching serial numbers to ensure zero prior field usage.
