HHR-30HF5G1 Yokogawa 6V 3000mAh DCS Backup Battery

Product Overview

The Yokogawa HHR-30HF5G1 acts as the primary power safeguard for CENTUM VP and CENTUM CS 3000 Distributed Control Systems. This high-capacity 6V battery pack sustains CPU modules and volatile memory boards during main power rail failures or routine maintenance cycles. By delivering a consistent 3000 mAh of backup energy, the HHR-30HF5G1 prevents catastrophic data loss and ensures the system retains its configuration and runtime variables. It serves as a critical component in maintaining 24/7 operational continuity for mission-critical industrial plants.

Technical Specifications

The HHR-30HF5G1 utilizes robust cell chemistry to meet the rigorous demands of industrial control cabinets:

Engineering Advantages

• High Energy Density: The 3000 mAh rating provides significantly longer backup windows compared to standard lithium cells. This gives maintenance teams ample time to restore main power without risking a "cold start" configuration loss.

• Industrial Thermal Resilience: Control cabinets often experience localized heat buildup. The HHR-30HF5G1 handles wide temperature fluctuations, preventing the premature capacity degradation common in consumer-grade battery packs.

• Deep Discharge Protection: The internal cell architecture resists the "memory effect," ensuring the battery delivers its full rated voltage even after multiple short-duration power cycles.

• Secure Integration: Designed specifically for the CENTUM rack architecture, the battery features the correct connector interface and mounting footprint to ensure vibration-resistant installation inside the I/O or CPU nest.

FAQs

Q1: How often should I replace the HHR-30HF5G1 battery pack?A1: Yokogawa typically recommends replacement every 2 to 5 years, depending on the ambient temperature of your control room. High-temperature environments accelerate chemical aging, so we suggest tracking the "Battery Low" alarms on your HIS (Human Interface Station).

Q2: Can I hot-swap this battery while the DCS is running?A2: Yes, provided the main system power remains stable. Replacing the battery during normal operation ensures the CPU never loses its backup source. Always verify the status LEDs on the CPU module after installation to confirm the new battery is recognized.

Q3: Why does the chemistry vary between NiMH and NiCd for this model?A3: Production batches vary based on updated environmental regulations and energy density requirements. Both versions maintain the exact same voltage and form factor, ensuring 100% functional compatibility with your HHR-30HF series hardware.

Q4: How do I ensure I am receiving a fresh, brand-new unit?A4: We supply only 100% Brand New and Original Yokogawa stock. Each HHR-30HF5G1 arrives in its original factory packaging with a traceable manufacturing date code to ensure you receive a unit with maximum service life.
