1769-PA2 Allen Bradley CompactLogix Power Supply Module
The Allen-Bradley 1769-PA2 is a compact, high-efficiency power supply module designed for the CompactLogix 1769 series of programmable logic controllers (PLCs). It converts 120/240V AC input power to 24V DC output, providing reliable energy for CompactLogix controllers (e.g., 1769-L23, L31, L35E) and their connected I/O expansion modules. As a critical component of the Compact I/O system, it ensures stable operation in industrial automation applications such as packaging machinery, pump stations, and material handling systems.
Key Features
Flexible Power Input
Wide Voltage Range: Supports 85-264V AC input (47-63Hz), compatible with global power standards
Dual Voltage Selection: Internal jumpers allow switching between 120V AC and 240V AC inputs, adapting to regional grid requirements
Stable DC Output
24V DC Supply: Delivers a nominal 24V DC output with a maximum current of 2.0A (48W power), sufficient for powering controllers and up to 16 local I/O modules
High Efficiency: Typical efficiency exceeds 75%, minimizing energy waste and heat generation
Robust Protection & Reliability
Comprehensive Safeguards: Built-in overcurrent (OCP), overvoltage (OVP), and short-circuit protection automatically shut down the module during faults, protecting downstream devices
Industrial Durability: Designed for harsh environments, with an operating temperature range of 0-60°C (32-140°F) and IP20 rating (requires enclosure use)
User-Friendly Design
Status Indicators: Green "POWER" LED confirms normal operation; red "FAULT" LED alerts to abnormalities (e.g., overloads, overheating)
DIN Rail Installation: Mounts easily on standard 35mm DIN rails, saving control cabinet space
Tool-Free Wiring: Screw terminal blocks for quick AC input and DC output connections
