YOKOGAWA PS35*A – DCS Rack Power Supply Module | Centum VP / CS3000 Platform
Engineering Background
The YOKOGAWA PS35*A is a dedicated rack-mount power supply module engineered for the Centum VP and CS3000 Distributed Control System (DCS) platforms — YOKOGAWA’s flagship process automation architectures deployed across refining, petrochemical, power generation, and pharmaceutical industries worldwide. Designed to deliver stable, conditioned DC power to field control stations (FCS) and I/O subsystems, the PS35*A is a critical infrastructure component where reliability directly impacts plant uptime and safety integrity.
Product Positioning
Procurement engineers sourcing PS35*A modules require verified OEM-grade parts with traceable provenance. Konmask.com maintains a curated inventory of YOKOGAWA automation components, offering B2B buyers direct access to genuine modules with full technical support, pre-shipment inspection, and documented quality verification — eliminating the risk associated with unverified grey-market supply chains.

- Compact Rack Form Factor — Optimized for YOKOGAWA standard cabinet layouts; no field modification required
System Architecture & Signal Flow
Within a Centum VP or CS3000 field control station, the PS35*A occupies a dedicated power slot in the FCS rack. AC mains input is conditioned and converted to regulated DC, distributed via the rack backplane to all installed I/O modules, communication cards, and the field control unit (FCU). In a redundant configuration, two PS35*A modules operate in parallel load-sharing mode; upon failure of one unit, the surviving module assumes full load without interruption — a critical requirement for SIL-rated and high-availability process loops.

Technical FAQ
Q: Is the PS35*A compatible with both Centum VP and CS3000?
A: Yes. The PS35*A power supply module is designed for use across the Centum VP and CS3000 DCS platforms. Verify your rack model and slot assignment against YOKOGAWA’s hardware compatibility matrix before installation.
Q: Can I use a single PS35*A without redundancy?
A: Yes, a single module is fully functional. Redundant configuration (dual PS35*A) is recommended for critical process loops and SIL-rated applications.
Q: What is the lead time for PS35*A?
A: In-stock units ship within 1–3 business days. For bulk orders or specific sub-variants, contact Konmask for availability confirmation.
Q: Do you provide a datasheet or YOKOGAWA documentation?
A: Yes. Contact [email protected] to request the official YOKOGAWA PS35*A datasheet and installation manual.
Q: Is this a new or refurbished module?
A: Konmask supplies both new OEM stock and professionally inspected surplus units. Condition is specified at time of quotation. All units pass pre-shipment functional verification.
Q: Can you support export to international destinations?
A: Yes. Konmask ships globally with full export documentation, commercial invoice, and packing list. HS code and country of origin documentation available on request.
