    • Backup Active (BKUP): Red (backup power active, main power lost); Off (main power normal)
• Environmental Ratings:
  • Operating Temperature Range: 0℃~+50℃ (32℉~122℉; optimal for Li-ion battery performance and longevity)
  • Storage Temperature Range: -20℃~+60℃ (-4℉~140℉; avoid prolonged storage at extreme temperatures)

  • Shock Resistance: 15g acceleration (11ms duration, IEC 60068-2-27; maintains battery integrity and electrical connections)
• Compliance Standards: IEC 62133 (safety for rechargeable Li-ion batteries), UL 1642 (lithium battery safety), CE, RoHS (restriction of hazardous substances)

2. Key Features

• Li-ion Battery Technology: High energy density and low self-discharge ensure reliable backup power (15–20 minutes) for AC 800M controllers, while avoiding the maintenance requirements of lead-acid batteries (e.g., water refilling).
• Seamless AC 800M Integration: Tool-less snap-in installation into AC 800M racks; derives charging power directly from the rack backplane (no external wiring required). Communicates battery health/status data to the AC 800M controller for remote monitoring.
• Comprehensive Protection Mechanisms: Built-in overcharge, overdischarge, and short-circuit protection safeguards the battery, AC 800M components, and personnel—preventing thermal runaway, battery swelling, or electrical damage.
• Intuitive Status Monitoring: Tri-color LEDs (charging, health, backup active) provide on-site technicians with real-time visibility into battery performance (e.g., identifying degraded batteries before failure). Status data is also transmitted to the DCS HMI for remote alerting.
• Long Service Life: ≥5 years of operational life and 200+ charge/discharge cycles reduce replacement frequency and maintenance costs—critical for remote or hard-to-access AC 800M installations (e.g., offshore platforms, remote power plants).
• Flame-Retardant Housing: UL94 V-0 rated plastic housing minimizes fire risk in control cabinets, complying with industrial safety standards for electrical equipment in hazardous process environments (e.g., chemical plants, oil refineries).
• Data Preservation Focus: Optimized output voltage (3.3V DC) and current (0.8A) ensure AC 800M controllers retain volatile data (e.g., PID loop states, process alarms) and execute controlled shutdown sequences—avoiding costly data loss and process restarts.

3. Application Fields

• AC 800M DCS Critical Installations: Primary application—provides backup power to AC 800M controllers in:
  • Chemical/Petrochemical Plants: Preserves reactor control logic and safety interlock states during power outages, preventing uncontrolled reactions or safety hazards.
  • Power Generation: Maintains turbine auxiliary control data (e.g., bearing temperature, lubrication pressure) to enable safe shutdown and avoid equipment damage.
  • Oil & Gas Refineries: Protects pipeline pressure control and storage tank level monitoring data, ensuring compliance with safety regulations during power disruptions.
• Remote Industrial Sites: Supports AC 800M systems in remote locations (e.g., offshore drilling rigs, mining sites) where power grid stability is poor—ensuring data integrity until backup generators activate.
• Water & Wastewater Treatment: Preserves pump control sequences and effluent quality monitoring data, preventing untreated wastewater discharge (a violation of environmental regulations) during power outages.
• Pharmaceutical Manufacturing: Maintains batch processing data (e.g., sterilization temperature, mixing time) in FDA/GMP-compliant facilities, avoiding product 报废 (scrap) and regulatory non-compliance.
• Food & Beverage Production: Protects pasteurization cycle data and filling machine control states, ensuring product safety and preventing contamination from interrupted processes.

4. Precautions

• AC 800M Compatibility: Use exclusively with ABB AC 800M DCS racks. Installation in non-AC 800M systems (e.g., AC 500 PLCs, third-party DCS) will cause voltage mismatches, charging failures, or damage to the module/battery.
• Temperature Limitations: Operate within 0℃~+50℃. Exposure to temperatures >50℃ accelerates Li-ion battery degradation (reducing capacity by 20–30% per year); temperatures <0℃ disable charging and reduce backup runtime.
• Charging Requirements: Ensure the AC 800M rack main power is active for ≥4 hours after module installation or battery replacement. Incomplete charging reduces backup runtime and shortens battery life.
• Battery Replacement Safety:
  • Replace only with the exact ABB SB808F module (3BDM000199R1). Using third-party batteries voids the AC 800M warranty and risks fire/explosion (due to incompatible chemistry or protection circuits).
  • Disconnect the AC 800M rack main power before replacing the module. Hot-swapping (replacing while powered) can cause electrical arcing, damaging the rack backplane or battery.
• Disposal Compliance: Treat spent modules as hazardous waste (per local regulations for Li-ion batteries). Do not incinerate, crush, or disassemble—contact ABB’s recycling program or certified e-waste handlers for proper disposal.
• Regular Health Checks: Monitor battery health via AC 800M HMI or on-module LED:
  • Replace the module if the HLTH LED turns amber (capacity 50–80%) to avoid unexpected backup failures.
  • Replace immediately if the HLTH LED turns red (faulty battery) to prevent potential leakage or electrical issues.
• Storage Guidelines: Store unused modules in a dry environment (20℃~25℃, 40–60% RH) with 50–70% charge. Avoid long-term storage at full charge (>90%)—this accelerates capacity degradation
