Process Automation Power Solution – YOKOGAWA SPW484-50 | Centum VP / CS 3000 Series
Where This Product Is Used
The YOKOGAWA SPW484-50 is a dedicated power supply module engineered for mission-critical distributed control system (DCS) environments. It is widely deployed in:
- Oil & Gas Refineries – Powering field controller stations and I/O bus segments in upstream/downstream process units
- Chemical & Petrochemical Plants – Sustaining 24/7 continuous process control loops where power interruption is unacceptable
- Pulp & Paper Mills – Supplying stable DC power to Centum VP field control units across large-scale production lines
- Power Generation Facilities – Integrated into turbine control and boiler management DCS cabinets
- Pharmaceutical Manufacturing – Supporting GMP-compliant automation systems requiring validated, stable power rails
- Water & Wastewater Treatment – Deployed in SCADA-linked DCS panels for pump and valve control

Application-Specific FAQ
Q: Is the SPW484-50 compatible with both Centum VP and CS 3000 systems?
A: Yes. The SPW484-50 is designed for the Centum VP platform and is backward-compatible with CS 3000 power bus configurations in most cabinet layouts. Verify your cabinet revision with YOKOGAWA documentation before installation.
Q: Can I run two SPW484-50 modules in parallel for redundancy?
A: Yes. The module supports N+1 hot-standby redundancy. In the event of a primary module failure, the standby unit assumes load without interrupting the control system.
Q: What is the expected service life of this module?
A: YOKOGAWA rates industrial power supply modules for 10+ years MTBF under normal operating conditions (25°C, rated load). Actual life depends on ambient temperature, load factor, and maintenance schedule.
Q: Do you provide a test report or inspection certificate?
A: Yes. Konmask can provide a pre-shipment inspection report upon request. Contact us before placing your order to arrange documentation.
Q: Can this module be used outside of YOKOGAWA DCS systems?
A: The SPW484-50 is optimized for YOKOGAWA Centum VP/CS 3000 bus architecture. Use in third-party systems is not recommended without consulting a qualified automation engineer.
