Key Features

1. Dual Isolated Outputs
   • Provides 5A at 12VDC and 5A at 24VDC simultaneously, powering both low-voltage logic and higher-voltage I/O devices.
   • Isolated outputs prevent cross-circuit interference and enhance system safety.
2. Wide-Range AC Input
   • Accepts 85–264 VAC input, supporting global power standards and voltage fluctuations without performance degradation.
3. Redundancy-Ready Design
   • Can be paired with a second 8913-PS-AC for 1:1 redundant operation, eliminating single points of failure in critical applications.
4. Intrinsic Safety & Hazardous Area Compliance
   • Certified for Class 1 Division 2 hazardous areas, ensuring safe operation in explosive gas, vapor, or dust environments.
5. Modular & Space-Saving
   • Compact DIN-rail form factor integrates directly into PAC8000 backplanes, requiring no additional wiring or terminals.
   • Hot-swappable design enables replacement without system shutdown.
6. Comprehensive Protection
   • Built-in overvoltage, overcurrent, short-circuit, and overtemperature safeguards protect connected I/O modules and ensure long-term reliability.
