Description

Uninterruptible Power Solution – YOKOGAWA S9400UK | Battery Pack

Where This Product Is Used

The YOKOGAWA S9400UK Battery Pack is a dedicated backup power module engineered for mission-critical distributed control system (DCS) environments. It is deployed wherever continuous process control must be maintained through power interruptions, grid instability, or planned maintenance shutdowns.

Typical deployment sites include:

Oil & Gas Refineries – Sustains CENTUM VP/CS 3000 field control stations (FCS) during grid fluctuations, preventing unplanned process trips.
Chemical & Petrochemical Plants – Provides ride-through power for safety-critical loops where a controller restart could trigger SIS activation.
Power Generation Facilities – Backs up turbine and boiler control nodes, ensuring operator visibility is maintained during switchgear events.
Pharmaceutical Manufacturing – Protects batch process controllers from data loss and recipe interruption during momentary outages.
Pulp & Paper Mills – Keeps continuous process controllers online during utility supply transitions.
Water & Wastewater Treatment – Maintains SCADA-linked DCS nodes through power quality events common in utility infrastructure.

Application-Specific FAQ

Q: Is the S9400UK compatible with both CENTUM VP and CENTUM CS 3000?
A: The S9400UK is a YOKOGAWA-designed battery pack intended for the CENTUM platform family. Please confirm your specific FCS model and power supply slot configuration with us before ordering to ensure dimensional and electrical compatibility.

Q: What is the expected backup duration provided by the S9400UK?
A: Backup duration depends on the connected load (number of I/O modules, FCS type, and ambient temperature). Refer to the YOKOGAWA S9400UK datasheet or contact our team for a load-specific calculation.

Q: Can I use a third-party battery as a replacement instead of the S9400UK?
A: YOKOGAWA does not recommend third-party battery substitutions for CENTUM power supply modules, as cell chemistry, voltage profile, and connector pinout are matched to the OEM design. Using non-OEM batteries may void system warranty and create safety risks.

Q: How do I know when the S9400UK battery needs replacement?
A: CENTUM VP/CS 3000 systems generate a battery alarm via the HIS (Human Interface Station) when battery capacity falls below threshold. YOKOGAWA also publishes recommended replacement intervals in the system maintenance manual.

Q: Do you supply S9400UK units with a warranty?
A: Yes. New and surplus-new units carry a standard Konmask supply warranty. Refurbished units carry a functional warranty. Contact us for specific warranty terms applicable to your order.

Q: Can you source multiple units for a plant-wide spare parts program?
A: Yes. Konmask supports bulk procurement for MRO and capital spares programs. Contact us with your full BOM for a consolidated quotation.
