    Allen Bradely 1756-PA75 - PLC-HUB Programmable Logic ...
    The Allen-Bradley 1756-PA75R is not a PLC programming controller but an AC redundant power supply for Allen-Bradley's ControlLogix PLC systems, providing reliable, uninterrupted power (75W) by operating in pairs (with a second unit and chassis adapter like the 1756-PSCA2) to ensure high availability in critical applications, delivering voltages like 5.1V, 3.3V, 1.2V, and 24V DC to the chassis backplane. It's a hardware component for the ControlLogix platform, not a device for writing code, and works with specific connection cables like the 1756-CPR2, with programming done using software like Rockwell Automation's Studio 5000 or RSLogix. 
    Key Functions & Features: 
    • Redundancy: Designed to work with a second 1756-PA75R to provide backup power; if one fails, the other takes over seamlessly.
    • High Availability: Critical for applications needing maximum uptime, preventing shutdowns due to power loss.
    • Remote Mounting: Installed outside the ControlLogix chassis, connected via a special cable to the chassis adapter.
    • Power Output: Delivers 75W, with various DC outputs (5.1V @ 13A, 3.3V @ 4A, 1.2V @ 1.5A, 24V @ 2.8A).
    • Input: Accepts 85–265V AC. 
    How it fits into ControlLogix: 
    1. Hardware: The 1756-PA75R is a module in the Allen-Bradley ControlLogix family (identified by the 1756 prefix), alongside processors, I/O modules, and communication cards.
    2. Programming Software: You program the logic for the entire system (processors, I/O) using Rockwell Automation's Studio 5000 or RSLogix software, not the power supply itself. 
    In summary, the 1756-PA75R is a reliable power module that ensures your ControlLogix system stays running, while the programming happens on the controller (processor) using dedicated software.
