The Allen-Bradley 1756-PA72/C ControlLogix Power Supply delivers redundant 24V DC power for mission-critical automation systems. Designed as a hot-swappable, dual-slot module for Rockwell Automation's ControlLogix chassis, it provides 72W of isolated power (3A continuous @ 24V DC) with N+1 redundancy support.
Its rugged aluminum housing (-40°C to +70°C) features integrated cooling fins and withstands 5g vibration (IEC 60068-2-6), ideal for harsh environments. The supply includes active current-sharing technology for parallel operation and embedded diagnostics for voltage/load monitoring. Key certifications include ATEX Zone 2 and SIL 2 compliance, ensuring reliable operation in hazardous locations and safety-critical processes.
