I. Product Overview

Rockwell Automation 1769-PA4 is a power supply module in the CompactLogix series, mainly providing stable and reliable DC power for controllers, I/O modules and other related components in the CompactLogix system, and it is the "power core" of the entire control system. It can convert external AC power into the DC voltage required by the system, ensuring that each module operates stably in industrial environments. The module adopts a modular design, perfectly compatible with 1769 series racks, with convenient installation and flexible deployment according to system configurations. It is widely used in various industrial automation scenarios such as machinery manufacturing, automated production lines, warehousing and logistics, and municipal engineering, providing continuous power guarantee for the efficient operation of the CompactLogix system.

II. Performance Parameters

Input Parameters:
Input Voltage: Supports AC input, with a common input range of 100-240V AC, compatible with power grid voltage standards in different regions. There is no need to replace the power module due to voltage differences, which improves the versatility of the equipment.
Input Frequency: Adapts to AC power frequency of 50/60Hz, and can work normally in most industrial power environments around the world.
Input Current: At 100V AC input, the typical input current is about 1.5A; at 240V AC input, the typical input current is about 0.75A. The specific value will fluctuate slightly due to load changes.

Output Parameters:
Output Voltage: Provides a stable 24V DC output, which is the standard working voltage for CompactLogix series controllers and most I/O modules, ensuring normal power supply for each module.
Output Current: The maximum continuous output current is 4A, which can meet the power supply needs of small and medium-sized CompactLogix systems and can provide power support for multiple I/O modules and controllers at the same time.
Output Ripple: The ripple coefficient of the output voltage is low, usually ≤100mV peak-to-peak, which ensures the stability of the output voltage, reduces interference to sensitive electronic components, and ensures the normal operation of the module.
Voltage Regulation Rate: When the input voltage and load change, the regulation rate of the output voltage is ≤±1%, which can effectively resist the impact of grid voltage fluctuations and load changes on the output voltage, maintaining the stability of power supply.

Efficiency and Power Consumption: It has high conversion efficiency, usually reaching more than 80% under rated load, which can effectively reduce energy loss and lower equipment operating costs. The no-load power consumption is low, which helps save energy.

Protection Function Parameters:
Overcurrent Protection: When the output current exceeds the rated value, the module will automatically enter the protection state, limit the output current, prevent damage to the power module and connected equipment due to overload, and the output can be automatically restored after the fault is eliminated.
Overvoltage Protection: If the output voltage rises abnormally beyond the set threshold (usually around 28V DC), the module will activate overvoltage protection and cut off the output to avoid damage to downstream modules caused by high voltage.
Short-Circuit Protection: When a short-circuit fault occurs at the output end, the module can respond quickly and cut off the output. After the short-circuit fault is eliminated, the output can be restored manually or automatically, protecting the safety of the power module and the entire system.

Environmental Parameters:
Operating Temperature: It can work stably in the temperature range of 0℃-60℃, adapting to temperature changes in common environments such as industrial production workshops and control cabinets, and can maintain stable output performance even in high-temperature environments.
Relative Humidity: It can operate normally in a relative humidity environment of 5%-95% (non-condensing), cope with humid industrial places, and effectively prevent circuit faults caused by humidity.
Anti-Electromagnetic Interference: It complies with industrial electromagnetic compatibility standards (such as IEC 61000-6-2), has a certain anti-electromagnetic interference capability, can resist electromagnetic interference in industrial sites, and ensure the stability of the output voltage.
Vibration and Shock Resistance: The vibration resistance range is 10-500Hz, with an amplitude of 0.38mm or an acceleration of 10g; the shock resistance range can reach 15g (11ms). It can withstand vibration and shock generated during the operation of industrial equipment, ensuring the stability of the module's structure and performance.

III. Functional Features

Stable and Reliable Power Supply Capacity: 1769-PA4 adopts advanced power conversion technology, which can stably convert AC input to 24V DC output, not significantly affected by input voltage fluctuations and load changes. It provides continuous and stable power for each module of the CompactLogix system, ensuring the normal operation of the system.

Comprehensive Protection Mechanism: It has multiple protection functions such as overcurrent, overvoltage and short-circuit protection, which can respond quickly in various abnormal situations, protect the power module itself and connected controllers, I/O modules and other equipment from damage, improve the safety and reliability of the system, and reduce fault downtime.

Convenient Installation and Integration: Adopting a modular design, it can be directly installed on 1769 series racks, with a simple and fast installation process, without complicated wiring and debugging. It is seamlessly compatible with other modules in the CompactLogix series, can quickly integrate into the system, and simplifies the system construction process.

Status Indication Function: The module is equipped with LED indicators, which can display the working status of the power supply in real time, such as normal power output (green light on), fault status (red light on or flashing), etc. Operators can quickly judge the operation of the power module by observing the status of the indicators, which is convenient for timely detection and troubleshooting.
Wide Range Input Adaptability: It supports a wide input voltage range of 100-240V AC, compatible with power grid standards in different regions. There is no need to replace the power module for applications in different regions, which improves the versatility and flexibility of the equipment, and reduces inventory and maintenance costs.
