Critical Process Control Solution — YOKOGAWA PSCCM22AAN | CENTUM CS/VP Series
Where This Product Is Used
The YOKOGAWA PSCCM22AAN is a Critical Control Module (CCM) designed for deployment in the CENTUM CS and CENTUM VP Distributed Control System (DCS) platforms. It serves as the central processing unit within Field Control Stations (FCS), executing real-time control logic, managing I/O communication, and maintaining process continuity in mission-critical environments.
Typical deployment sites include:
- Oil & Gas Upstream/Downstream: Wellhead control, separator automation, refinery distillation column regulation
- Petrochemical & Chemical Plants: Reactor temperature/pressure loop control, batch process sequencing
- Power Generation: Boiler combustion control, turbine governor interfacing, load dispatch automation
- Pulp & Paper / Pharmaceuticals: Continuous process control requiring high-availability CPU redundancy
- Water & Wastewater Treatment: Multi-loop PID control for dosing, filtration, and flow management

Why Engineers Specify This Model
- Proven Redundancy Architecture: The PSCCM22AAN supports hot-standby dual-CPU redundancy, enabling bumpless switchover in under 1 second — critical for processes where downtime costs exceed tens of thousands of dollars per hour.
- Seamless CENTUM Ecosystem Integration: Plug-compatible with existing CENTUM CS and VP FCS racks, eliminating costly re-engineering when replacing aging CCM modules.
- High-Throughput Control Execution: Handles complex multi-loop PID, cascade, ratio, and feedforward control schemes within a single module, reducing rack footprint.
- Long-Term Supportability: YOKOGAWA’s extended lifecycle support policy ensures spare parts availability and firmware compatibility for 10+ year plant lifecycles.
- Deterministic Scan Cycle: Fixed-cycle execution guarantees predictable control response — essential for safety-instrumented and regulatory-compliance applications.

Application-Specific FAQ
Q: Is the PSCCM22AAN compatible with both CENTUM CS and CENTUM VP systems?
A: Yes. The PSCCM22AAN is designed for use across the CENTUM CS and CENTUM VP FCS platforms. Always verify your FCS firmware version and rack type before installation to confirm slot compatibility.
Q: Can I use a single PSCCM22AAN without redundancy?
A: Yes, simplex (non-redundant) operation is supported. However, for SIL-rated or continuous-process applications, dual-redundant CCM configuration is strongly recommended per IEC 61511 guidelines.
Q: What is the typical lead time for this module?
A: In-stock units ship within 1–3 business days. For out-of-stock scenarios, lead time is typically 4–12 weeks depending on global supply. Contact us for real-time availability.
Q: Do you provide a warranty?
A: We offer a 30-day DOA guarantee. For extended warranty coverage or on-site commissioning support, please inquire via email.
Q: Can Konmask assist with CENTUM VP system migration or upgrade projects?
A: Yes. Our technical team can assist with BOM compilation, cross-referencing legacy CENTUM CS modules to VP equivalents, and sourcing complete FCS node assemblies. Reach out with your project scope.
