YOKOGAWA 16418-541/1 PSCCM24AAN – Power Supply & Critical Control Module | CENTUM VP / CS 3000
Engineering Background
The YOKOGAWA CENTUM VP and CS 3000 platforms represent the gold standard in distributed control system (DCS) architecture for process-critical industries including oil & gas, petrochemical, power generation, and pharmaceutical manufacturing. Within these platforms, the power supply and critical control module (PSCCM) series serves as the backbone of field controller cabinet power integrity — ensuring uninterrupted 24 VDC regulated output to all downstream I/O and processor modules.
Product Positioning
The 16418-541/1 PSCCM24AAN is a factory-configured power supply critical control module designed for direct integration into YOKOGAWA FCS (Field Control Station) cabinets. It is engineered for procurement engineers and system integrators who require a verified, drop-in replacement or expansion unit with full compatibility assurance for live production environments.

System Architecture & Signal Flow
Within the CENTUM VP FCS cabinet, the PSCCM24AAN receives AC mains input (via the cabinet power distribution unit) and converts it to a regulated 24 VDC bus. This bus feeds:
- Field Control Unit (FCU) processor cards
- Analog and digital I/O modules (ALF111, AAI141, ADV151, etc.)
- Communication interface modules (ESB bus, ER bus)
- Redundant module pairs where applicable
The PSCCM module integrates with the cabinet’s power monitoring logic, providing status signals to the system’s self-diagnostic layer for predictive maintenance alerting.
Sourcing & Quality Verification

Technical FAQ
Q: Is the 16418-541/1 PSCCM24AAN compatible with both CENTUM VP and CS 3000?
A: Yes. The PSCCM24AAN module is cross-compatible with both CENTUM VP R4/R5/R6 and CENTUM CS 3000 R3 FCS cabinet configurations. Verify your cabinet revision with YOKOGAWA documentation before installation.
Q: Can this module operate in a redundant power supply configuration?
A: The suffix “AN” denotes a non-redundant (single) unit. For redundant configurations, two PSCCM24AAN units are installed in parallel with a load-sharing diode assembly — consult your CENTUM VP hardware manual (IM 33J01B10-01E) for wiring details.
Q: What is the typical lead time for this part?
A: Konmask maintains surplus stock. Standard dispatch is 2–5 business days after payment confirmation. Express dispatch (next business day) available upon request.
Q: Do you provide a test report or certificate of conformity?
A: Yes. A functional test report and certificate of conformity are available upon request at no additional charge.
Q: What warranty terms apply?
A: All verified surplus units carry a 90-day warranty covering functional defects. Units must be returned in original packaging with fault description for warranty assessment.
