Description

Product Description

YOKOGAWA CP461-50 S1 is a high-performance operator interface terminal (HMI) from Yokogawa’s ProSafe-RS and CENTUM VP automation ecosystems, designed for critical process control applications in oil & gas, chemical, and power generation industries. As a core visualization component for Yokogawa’s DCS (Distributed Control Systems), YOKOGAWA CP461-50 S1 features a 15.6-inch widescreen TFT LCD display with anti-glare coating, enabling clear process monitoring even in high-light industrial environments. Unlike generic HMIs, YOKOGAWA CP461-50 S1 is factory-optimized for seamless communication with Yokogawa’s CENTUM VP DCS and ProSafe-RS safety systems, supporting real-time data exchange for process variables, alarm notifications, and safety interlock status [Product Link: Please supplement], where you can access the terminal’s system integration guide and alarm configuration manual. In practical applications, YOKOGAWA CP461-50 S1 is deployed in refinery distillation unit control, chemical reactor monitoring, and power plant boiler operation, working alongside Yokogawa’s PLCs and transmitters to provide operators with reliable process oversight. Additionally, YOKOGAWA CP461-50 S1 boasts a rugged design compliant with IEC 61508 (SIL 2) for safety-critical use, redundant power inputs, and support for Yokogawa’s ExaOperation software, making it a trusted solution for continuous process industries with zero-downtime requirements.

Advantages and Features

  1. Safety-Critical Compliance: YOKOGAWA CP461-50 S1 is certified to IEC 61508 SIL 2 and ATEX Zone 2, making it suitable for use in hazardous process environments (e.g., refineries, chemical plants) where safety is paramount.
  2. Redundant Design: Dual Gigabit Ethernet ports and redundant power inputs ensure uninterrupted operation and communication, critical for continuous process industries with minimal downtime tolerance.
  3. Seamless Yokogawa Ecosystem Integration: Native support for CENTUM VP DCS and ProSafe-RS safety systems eliminates the need for third-party gateways, reducing system complexity and integration time.
  4. High-Visibility Display: 15.6-inch Full HD anti-glare display delivers clear process visuals even in bright industrial settings, while 10-point multi-touch enables intuitive operation of complex control screens.
  5. Rugged Industrial Build: IP54 front-panel protection against dust and water spray, combined with wide temperature tolerance, ensures reliable performance in harsh process control environments.
  6. Advanced Alarm Management: Integration with Yokogawa’s ExaOperation software enables real-time alarm prioritization, event logging, and root-cause analysis, improving operator response to critical process issues.

Application Fields and Cases

Core Application Fields

  • Oil & Gas Industry: Refinery distillation unit monitoring, pipeline pressure control, LNG plant process visualization
  • Chemical Industry: Reactor temperature/pressure monitoring, batch process control, hazardous material handling oversight
  • Power Generation Industry: Boiler operation control, turbine status monitoring, nuclear power plant auxiliary system visualization
  • Water & Wastewater Industry: Treatment plant process control, pump station monitoring, water quality parameter tracking

Typical Application Case

In a Middle Eastern oil refinery’s distillation unit modernization project, the plant deployed YOKOGAWA CP461-50 S1 terminals to replace legacy operator stations, integrating with a CENTUM VP DCS and ProSafe-RS safety system. YOKOGAWA CP461-50 S1 provided real-time visualization of column temperatures, pressures, and flow rates, with multi-touch controls allowing operators to adjust setpoints and acknowledge alarms quickly. The terminal’s redundant power and Ethernet inputs prevented downtime during a utility outage, and its SIL 2 certification ensured compliance with the refinery’s safety standards. YOKOGAWA CP461-50 S1 reduced operator response time to critical alarms by 30% and improved overall process stability by 15%, resulting in a 10% reduction in unplanned shutdowns [Product Link: Please supplement] (see the project’s safety audit report and operational efficiency metrics).

Selection Suggestions

  1. Ecosystem Compatibility: Prioritize YOKOGAWA CP461-50 S1 for existing Yokogawa CENTUM VP/ProSafe-RS installations; choose Emerson DeltaV Operate HMI for Emerson DCS deployments.
  2. Hazardous Environment Needs: Select YOKOGAWA CP461-50 S1 for ATEX Zone 2 hazardous areas; non-hazardous process environments may use standard HMIs.
  3. Redundancy Requirements: Use YOKOGAWA CP461-50 S1 for continuous process industries (oil & gas, chemicals) requiring dual Ethernet/power inputs; single-redundancy systems may opt for simpler terminals.
  4. Display Quality Needs: Choose YOKOGAWA CP461-50 S1 for Full HD anti-glare displays in high-light environments; lower-resolution displays suffice for dimly lit control rooms.
  5. Spare Parts Planning: Reserve one YOKOGAWA CP461-50 S1 terminal per 5 process units to ensure quick replacement in case of hardware failure, especially in remote refinery/power plant locations.

Precautions

  1. Mount YOKOGAWA CP461-50 S1 using Yokogawa’s certified mounting kit to ensure proper ventilation and compliance with ATEX Zone 2 installation requirements (if applicable).
  2. Use shielded Gigabit Ethernet cables for communication with CENTUM VP DCS to minimize electromagnetic interference in industrial process environments.
  3. Configure alarm priorities and notification settings via ExaOperation software to align with the plant’s safety management system and regulatory requirements.
  4. Perform regular firmware updates via Yokogawa’s official support portal to patch security vulnerabilities and ensure compatibility with the latest CENTUM VP releases.
  5. Clean the anti-glare display with a soft, lint-free cloth and mild glass cleaner (avoid ammonia-based products) to preserve visibility and scratch resistance.
  6. Store spare terminals in a dry, temperature-controlled environment (-20°C ~ 60°C) with anti-static packaging to prevent damage to internal components during storage.
