8AC110.60-2 B&R – Intelligent power management, perfectly compatible with B&R systems, plug and play!

Description

The B&R 8AC110.60-2 is a high-availability, redundant power supply module engineered for mission-critical automation systems within B&R’s X20 platform. Designed to deliver uninterrupted 24 V DC power to backplanes and I/O modules, this unit features dual independent AC inputs (100–240 V AC) with active redundancy – enabling seamless failover during mains failure or voltage dips. Its integrated supercapacitor buffer provides 20 ms holdup time to bridge short outages, preventing system resets in sensitive processes like semiconductor manufacturing or pharmaceutical filling lines. With 60 W output power (2.5 A continuous) and 92% efficiency, the B&R 8AC110.60-2 minimizes heat generation while supporting hot-swap replacement for zero-downtime maintenance. Advanced diagnostics monitor input voltage, load current, temperature, and buffer status, relaying real-time health data via X2X Link to B&R’s Automation Studio for predictive maintenance.

Certified for SIL 2 safety applications, this module operates across -25°C to +60°C with derating above 50°C. Its compact 25 mm width integrates seamlessly with X20 I/O modules, while screw-clamp terminals simplify wiring. The B&R 8AC110.60-2 exemplifies ABB’s commitment to resilient infrastructure, ensuring control systems survive grid instability and hardware faults without disruption.

Technical Specifications

Main Features and Advantages

True Redundancy with Intelligent Load Sharing: The B&R 8AC110.60-2 employs active current balancing across parallel units, ensuring equal wear and eliminating single points of failure. If one module fails or loses input power, the other instantly takes full load without voltage dip – critical for safety systems requiring uninterrupted operation.

Ultra-Fast Buffering: Integrated supercapacitors provide 20 ms ride-through during brownouts, far exceeding standard PSUs (typically 3–5 ms). This prevents controller reboots during motor startups that cause voltage sags.

Advanced Diagnostics & Hot-Swap: Real-time monitoring of voltage, current, temperature, and capacitor health enables predictive maintenance. Front-panel LEDs indicate operational status (green), warnings (yellow), and faults (red). Modules can be replaced live via hot-swap without disrupting connected I/O.

Energy-Efficient Design: 92% efficiency reduces heat dissipation by 40% compared to conventional PSUs, enabling higher cabinet packing density. Natural convection cooling eliminates fan noise and dust accumulation.

Application Field

The B&R 8AC110.60-2 is indispensable in industries where power interruptions cause catastrophic losses:

Pharmaceuticals: Maintains sterility in filling lines by preventing shutdowns during grid fluctuations.

Semiconductor: Protects wafer processing equipment from microsecond power glitches ruining batches.

Oil & Gas: Ensures continuous safety system (ESD/F&G) operation on offshore platforms with unstable generators.

Automotive: Prevents robotic welding cell stoppages during spot-welding surges that sag facility voltage.

Food & Beverage: Avoids CIP system halts during steam valve actuation transients.

Power Plants: Backs up turbine control systems during switchgear operations.
