Allen-Bradley 1719-PSDC Intrinsically Safe DC Power Supply

The Allen-Bradley 1719-PSDC Intrinsically Safe DC Power Supply provides a 24 VDC output to Ex I/O modules in hazardous locations, specifically engineered for Zone 2/Class I, Division 2 environments within Allen-Bradley 1719 Ex I/O distributed I/O systems. It supports parallel operation with up to three power supplies for N+1 redundancy and automatic power sharing, helping maintain operation in the event of a single unit fault. The unit supports vertical or horizontal mounting to fit common 1719 Ex I/O chassis and is designed to maintain intrinsic safety across Ex i circuits, aligning with safety requirements for intrinsically safe power distribution. As part of Rockwell Automation's Ex I/O portfolio, this power supply is intended to deliver safe, regulated DC power to intrinsically safe I/O modules in hazardous-area control schemes, enabling reliable field wiring where energy and fault isolation must be tightly controlled.
