YOKOGAWA SPW482-50 – Redundant Power Supply Module | CENTUM CS/CS3000 DCS Platform
Engineering Background: The SPW482-50 is a dedicated redundant power supply module designed for YOKOGAWA’s CENTUM CS and CENTUM CS3000 Distributed Control Systems (DCS). It provides stable, conditioned DC power to field control stations (FCS) and I/O modules, ensuring uninterrupted process control in mission-critical industrial environments. As a core infrastructure component, it supports hot-standby redundancy configurations that eliminate single points of failure in power delivery.
Product Positioning: Targeted at process industries requiring 24/7 continuous operation — including oil & gas, petrochemical, power generation, and pharmaceutical manufacturing — the SPW482-50 is the OEM-specified power backbone for CENTUM CS/CS3000 field stations. Konmask.com supplies this module with full traceability and quality verification for MRO procurement and system expansion projects.

Diagnostic Visibility:
Status LEDs provide real-time health indication; fault signals propagate to CENTUM HIS operator station for predictive maintenance
System Architecture & Signal Flow
In a standard CENTUM CS3000 field station, the SPW482-50 occupies the dedicated power supply slot of the FCS baseplate. AC mains feed the module’s universal input stage, which rectifies and regulates to a stable 24 V DC bus. This bus powers all I/O modules (analog input/output, digital I/O, communication cards) installed in the same FCS nest. In redundant configurations, two SPW482-50 units share the load; the standby unit monitors bus voltage continuously and assumes full load within milliseconds of detecting a primary fault — maintaining uninterrupted power to all connected field devices and control loops.

Technical FAQ
Q: Can the SPW482-50 be used in a non-redundant single-supply configuration?
A: Yes. A single SPW482-50 can power an FCS nest independently. Redundant pairing is recommended for critical loops but is not mandatory for all installations.
Q: Is the SPW482-50 compatible with CENTUM VP?
A: The SPW482-50 is specified for CENTUM CS and CS3000 platforms. CENTUM VP uses a different power supply architecture (e.g., PW481/PW482 series for VP FCS). Confirm your FCS model before ordering.
Q: What happens during a power supply switchover in redundant mode?
A: The standby module detects bus voltage drop and assumes full load within milliseconds. The CENTUM HIS generates a system alarm for maintenance notification, but process control continues without interruption.
Q: Can Konmask provide a test report or inspection certificate?
A: Yes. A functional test report is available upon request at time of order. Third-party inspection can be arranged for large-volume orders.
Q: What is the lead time for SPW482-50?
A: In-stock units ship within 3–5 business days. For out-of-stock situations, lead time is confirmed at RFQ stage — typically 2–4 weeks for sourced units.
