DCS Backup Power Solution – YOKOGAWA S9185FA | CENTUM VP / CS 3000 Series
Where This Product Is Used
The YOKOGAWA S9185FA is a dedicated lithium backup battery module engineered for mission-critical distributed control system (DCS) environments. It is deployed across the following industrial sectors and applications:
- Oil & Gas Refineries — Sustains CENTUM VP/CS 3000 controller memory and real-time clock (RTC) during planned shutdowns, power outages, or UPS switchover events.
- Petrochemical & Chemical Plants — Protects process parameter retention in field control stations (FCS) where loss of configuration data causes costly re-commissioning.
- LNG Terminals & Offshore Platforms — Provides cold-start protection for remote DCS nodes where grid power is intermittent or subject to harsh environmental conditions.
- Power Generation (Thermal, Nuclear, Hydro) — Maintains controller integrity during turbine trip events and emergency shutdowns (ESD).
- Pharmaceutical & Fine Chemical Manufacturing — Ensures GMP-compliant data retention for batch process controllers under 21 CFR Part 11 audit requirements.
- Pulp, Paper & Water Treatment — Supports continuous process controllers in facilities with frequent utility fluctuations.

Application-Specific FAQ
Q: How do I know when the S9185FA battery needs replacement?
A: CENTUM VP and CS 3000 systems generate a low-battery alarm via the HIS (Human Interface Station) or PRM. YOKOGAWA recommends proactive replacement every 3–5 years regardless of alarm status during scheduled turnarounds.
Q: Can I replace the battery while the controller is powered?
A: Hot-swap capability depends on the specific FCS card model. Refer to YOKOGAWA’s hardware maintenance manual (IM 33S01B30-01EN or equivalent) for your controller revision. Konmask’s technical team can advise on safe replacement procedures.
Q: Is the S9185FA compatible with CENTUM 3000 (legacy) as well as CENTUM VP?
A: The S9185FA is primarily specified for CS 3000 and CENTUM VP platforms. For legacy CENTUM 3000 (pre-CS 3000), confirm the exact card part number with our team before ordering.
Q: What happens if the battery fails without replacement?
A: Controller SRAM data (including tuning parameters, tag configurations, and process values) and the real-time clock will be lost upon the next power cycle. Full re-download from the engineering workstation will be required, causing unplanned downtime.
Q: Do you supply batteries for other YOKOGAWA product lines?
A: Yes. Konmask stocks backup batteries and consumable spares for YOKOGAWA STARDOM, ProSafe-RS, EJX/EJA transmitters, and DAQSTATION recorders. Contact us with your full BOM for consolidated sourcing.
Q: Can Konmask provide a Certificate of Conformance (CoC)?
A: Yes. CoC, packing list, and lot traceability documentation are available for all genuine parts upon request at time of order.
