Product Description

The PM1*C (Part Number: S9380BP) is a legacy high-reliability control component designed for the Yokogawa CENTUM XL Distributed Control System (DCS). Engineered to serve as either a primary control processor or a specialized interface unit depending on the rack configuration, this module manages complex signal processing and real-time logic execution. It is built to the rigorous standards of 1980s and 90s industrial computing, featuring a robust architecture that remains a staple in operational maintenance for mature refineries and chemical processing facilities worldwide.

As an essential part of the CENTUM XL infrastructure, the PM1*C facilitates high-speed data throughput between the system bus and field I/O stations. Its design emphasizes thermal stability and long-term electrical durability, ensuring that legacy control loops continue to operate with the deterministic timing required for volatile industrial processes.

Detailed Technical Specifications

Legacy Support and Maintenance

Because the CENTUM XL series is now in its extended lifecycle phase, the PM1*C (S9380BP) is a critical asset for facility managers looking to avoid costly full-system migrations. These modules are frequently utilized as direct replacements to maintain the integrity of existing safety and control strategies without requiring software re-engineering.

Technical FAQ

• Question: Can the PM1*C be used in modern CENTUM VP systems?
  Answer: No. The PM1*C is specifically designed for the proprietary bus architecture of the CENTUM XL series. For CENTUM VP systems, a migration to the CP4x series or similar modern processors is required.

• Question: What does the S9380BP part number refer to?
  Answer: S9380BP is the specific spare part ordering number for the PM1*C module, ensuring that the hardware revision matches the technical requirements of the original system installation.
