Process Automation Solution – YOKOGAWA CP401-11 S1 | CENTUM CS3000
Where This Product Is Used
The YOKOGAWA CP401-11 S1 is a central processor (CPU) module designed for the CENTUM CS / CS3000 Distributed Control System (DCS) platform. It is deployed in mission-critical process industries where continuous, high-reliability control is non-negotiable:
- Oil & Gas Refineries – Crude distillation unit (CDU) control, compressor sequencing, and safety interlock coordination
- Petrochemical & Chemical Plants – Reactor temperature/pressure loop management, batch process control
- Power Generation – Boiler combustion control, turbine governor loops, load dispatch automation
- Pulp & Paper Mills – Digester control, bleaching sequence automation, stock flow regulation
- Pharmaceutical Manufacturing – GMP-compliant batch control, clean-in-place (CIP) automation
- Water & Wastewater Treatment – SCADA-integrated pump station control, dosing automation
- LNG / LPG Terminals – Cryogenic process monitoring, loading arm control, ESD integration

Application-Specific FAQ
Q: Is the CP401-11 S1 compatible with CENTUM CS (original) as well as CS3000?
A: The CP401-11 series was introduced for CENTUM CS3000. Compatibility with earlier CENTUM CS revisions depends on firmware and nest hardware revision — contact us with your existing FCS model number for confirmation.
Q: Can this module be used in a redundant CPU configuration?
A: Yes. CENTUM CS3000 FCS supports dual-redundant processor configurations. Two CP401-11 units are required; the system performs automatic bumpless switchover on fault detection.
Q: What is the difference between CP401-11 and CP401-10?
A: The S1 suffix denotes a specific hardware revision with updated memory capacity and enhanced communication handling. Always match the revision to your existing FCS configuration to ensure compatibility.
Q: Do you provide warranty on used/refurbished units?
A: Yes — all tested units carry a 90-day functional warranty. New old-stock (NOS) units carry a 12-month warranty. Terms available in writing upon request.
Q: Can you ship to our plant site internationally?
A: Yes. We ship globally via DHL Express, FedEx International Priority, and sea freight for bulk orders. Export compliance documentation is included.
