The Allen-Bradley 1756-PB72-24V ControlLogix® Power Supply delivers 24V DC output for mission-critical industrial systems, designed explicitly for powering distributed I/O networks and sensors in Rockwell Automation ecosystems. Supporting hot-swap N+1 redundancy, this 72W module converts dual-range AC input (85-132V AC or 170-265V AC) or 125-250V DC into stabilized 24V DC with 1% voltage regulation. Its rugged die-cast housing (-40°C to +70°C) features IP54 protection, cooling fins, and vibration-damped mounts for harsh environments. Integrated predictive diagnostics (LED status indicators and backplane tags) enable real-time health monitoring via Studio 5000®.
