The Allen-Bradley 1756-BA2 Battery Assembly is a mission-critical backup solution designed exclusively for ControlLogix ® L7x Series processors (L71/L72/L73/L75/L76). This lithium-based battery module provides volatile memory retention during unexpected power loss, preventing costly program or data corruption in industrial automation systems.
Featuring military-grade thionyl chloride (Li-SOCl₂) chemistry, it ensures fail-safe operation across extreme temperatures (-40°C to +85°C) without derating. The compact, slot-mounted design integrates seamlessly with processor housings, while its epoxy-sealed ABS case eliminates leakage risks. A built-in thermal fuse and current-limiting resistor provide redundant protection against overcurrent events, meeting rigorous UN/DOT 38.3 transport standards for hazardous environments.
Performance and safety parameters:
- Voltage/Capacity: 3.6V DC nominal / 1200 mAh (at +25°C)
- Retention Duration: Minimum 10 years shelf life / ≥3 months memory backup post-power loss
- Environmental Resilience: Operates at 85 °C ambient (non-condensing) / withstands 50g mechanical shock
- Compatibility: Exclusive support for 1756-L7x CPUs (requires firmware v20+)
- Electrical Protections: 7V minimum backup voltage threshold / 100μA standby current
- Safety Certifications: UL 2054, IEC 60086-4, RoHS 3 compliant
- Connection: Gold-plated contacts with 100,000+ mating cycles
- MTBF: >500,000 hours (57+ years) per MIL-HDBK-217F calc
Preventing catastrophic system failures:
- Energy Sector: Substation RTU program retention during grid blackouts
- Automotive Production: Preserving robotic weld path data in paint shops (ISO 13849)
- Pharmaceutical: Batch recipe continuity in freeze-dryer control systems (FDA 21 CFR Part 11)
- Continuous Process Lines: Paper mill PLC memory backup during voltage sags
- Material Handling: AS/RS crane position registry during E-stop events
- Critical Infrastructure: Water treatment SCADA historian preservation
Engineering innovations:
- Zero-Maintenance Design: 10-year continuous service without capacity checks
- Extreme Environment Operation: Functions in desert heat (+85°C) & arctic cold (-40°C)
- Secure Data Integrity: FRAM-compatible voltage regulation prevents brownout corruption
- Lifecycle Cost Savings: Eliminates capacitor replacements (saves $2k+/decade)
- Hot-Swap Capability: Replacement without processor shutdown (live removal at >7V DC)
- Compact Integration: 45mm width slots directly into CPU without cabling
- Cyber-Physical Security: Tamper-evident housing deters unauthorized access
Intelligent power management:
- Predictive Diagnostics: Processor triggers Major Fault (Code 16) at <20% capacity
- Status Indication: Solid green LED (operational) / Off (depleted)
- Voltage Clamping: Precision cutoff prevents deep-discharge battery damage
- Memory Protection: Non-volatile storage of:
- User programs
- Tag database values
- Recipe parameters
- Security keys
- Axis position data
- Seamless Transfer: Auto-switches between line power/battery in <1ms
- Legacy Migration: Compatible with 1756-BA1 retrofit kits
