YOKOGAWA S9548FA – Backup Battery Module | CENTUM VP / CS 3000 DCS Platform
Engineering Background
The YOKOGAWA S9548FA is a dedicated backup battery module engineered for use within YOKOGAWA’s CENTUM VP and CS 3000 Distributed Control System (DCS) platforms — two of the most widely deployed process automation architectures in refining, petrochemical, power generation, and pharmaceutical manufacturing. In mission-critical control environments, uninterrupted power continuity is non-negotiable. The S9548FA provides the last line of defense against data loss and controller shutdown during mains power interruptions, ensuring seamless process continuity and safe system state retention.
Product Positioning
Designed as a direct OEM replacement for aging or depleted battery modules in installed CENTUM VP and CS 3000 field cabinets, the S9548FA is the correct procurement choice for maintenance engineers performing scheduled battery replacement cycles, system upgrades, or emergency spares replenishment. Konmask.com sources this module through verified industrial supply channels, offering procurement engineers a reliable alternative to extended OEM lead times.

System Architecture & Signal Flow
Within the CENTUM VP / CS 3000 architecture, the S9548FA battery module is installed in the Field Control Station (FCS) or equivalent controller chassis. During normal operation, the module remains on float charge via the system power supply bus. Upon detection of mains power loss, the battery module autonomously assumes the load, sustaining controller logic, I/O scan cycles, and communication bus activity for the OEM-specified backup duration. No operator intervention is required for switchover. The module interfaces directly with the YOKOGAWA power supply board via the standard backplane connector.
