Features:
- ControlLogix 1756 identity: 1756-PA72 belongs to the documented ControlLogix 1756 family.
- Configuration: 85...265 V AC, 47...63 Hz input, 75 W maximum output, with 24 V, 5.1 V, 3.3 V and 1.2 V DC backplane outputs.
- Verification focus: Confirm catalog number, series, input supply, chassis type, power-load calculation, and nonredundant architecture before replacement.
Allen-Bradley 1756-PA72 is standard nonredundant ac chassis power supply designed for ControlLogix chassis-based control systems. According to the manufacturer documentation, it accepts 85...265 V AC and provides the regulated backplane power rails required by the ControlLogix chassis. The ordering code identifies catalog number, series, input supply, chassis type, power-load calculation, and nonredundant architecture, so the complete nameplate information should be reviewed whenever the item is being selected for a maintenance replacement, a system extension, or a spare-parts holding.
The technical content for 1756-PA72 is limited to the manufacturer product page and the cited official datasheet or manual. Final compatibility depends on the ControlLogix chassis, total backplane power demand, input branch circuit, enclosure, and required redundancy strategy.
The Allen-Bradley 1756-PA72 standard nonredundant AC chassis power supply is supported by Moore Automated for verified industrial replacement and spare-part requirements.

Compatibility Checks
Confirm the ControlLogix chassis, total backplane power demand, input branch circuit, enclosure, and required redundancy strategy. The complete 1756-PA72 marking and nameplate data should be compared with the installed item before a purchase order is released.
Installation Planning
Follow the manufacturer instructions and verify branch protection, AC wiring, protective earth, chassis mounting, and backplane power budget. Accessories, connectors, cables, sockets, or terminal blocks must be ordered separately unless the quotation lists them.
