Product Description

Engineered with high-reliability Nickel-Metal Hydride chemistry to safeguard mission-critical process data, the Yokogawa HHR-11F2A1 (S9129FA) backup battery directly prevents catastrophic configuration loss during plant-wide blackouts. Unlike consumer-grade secondary cells, this industrial-grade 2.4V retention module provides continuous volatile SRAM backup for CENTUM VP and CS 3000 CPU cards. It is the definitive choice for preventing expensive system re-initializations in continuous-process industries such as oil refining, power generation, and chemical synthesis.

Technical Specifications & Value-Driven Parameter Interpretation

Parameter	Technical Value	Practical Procurement Value & Project Benefit
Cell Voltage	2.4 VDC (Dual-Cell Configuration)	Perfectly matches the specific hardware thresholds of CENTUM memory circuits, eliminating data corruption risks caused by minor voltage drops.
Battery Chemistry	Nickel-Metal Hydride (Ni-MH)	Avoids the restrictive transportation regulations and environmental disposal overhead linked to older Lithium or Ni-Cd batteries, simplifying site procurement.
Target Application	SRAM CPU Memory Data Retention	Ensures your custom PID loops, sequence logic, and real-time plant parameters remain fully intact for hours during total control cabinet power failure.

Engineering Insights & Deployment Reliability

Engineer's Note

"DCS CPU batteries are often overlooked until a full shutdown happens and the rack loses its logic. When swapping out an older HHR-11F2A1, always perform the replacement while the cabinet is completely powered up and online. Removing the battery from a dead, unpowered CPU rack will instantly wipe the volatile SRAM, forcing you to undergo a lengthy and stressful cold-start download from your engineering station."

— Principal Automation Systems Architect

Project Case Study

Deployment Site: Liquefied Natural Gas (LNG) Terminal, Ras Laffan, Qatar (Serviced: 2025)
Operational Context: The HHR-11F2A1 was deployed as part of a routine preventative maintenance cycle within a CENTUM CS 3000 field control station. During a scheduled regional substation upgrade that kept the primary control cabinet completely unpowered for close to 4 hours, the backup battery successfully maintained the entire system configuration. The CPU rebooted flawlessly with zero logic errors once the primary grid line returned.

Customization FAQ

Q: What is the typical service life of the HHR-11F2A1 battery inside a running cabinet?

A: Under optimal climate-controlled conditions (ambient temperatures around 25°C), these Ni-MH cells typically offer a dependable operational lifespan of 3 to 5 years. However, if your cabinet runs continuously hot—exceeding 45°C—the internal cell degradation accelerates, and the replacement cycle should be shortened to every 2 years to stay safe.

Q: Can I use a standard 2.4V consumer AA rechargeable battery pack as a substitute?

A: Absolutely not. The HHR-11F2A1 utilizes highly specialized, low-self-discharge industrial cells equipped with an identical proprietary keyed connector harness and specific thermal protection. Standard commercial battery packs lack these exact dimensions, cannot handle sustained industrial cabinet temperatures, and risk leaking corrosive materials onto expensive CPU motherboards.

Q: How do I know if the battery needs to be replaced before a total failure occurs?

A: The CENTUM VP / CS 3000 system diagnostics will flag an active system alarm on your Human Interface Station (HIS) console, stating "Battery Low" or a corresponding system status code. Do not clear or ignore this alarm—it means the system has detected that the cell's voltage has fallen below its critical retention threshold.
