Application Scenarios

This power supply excels in process control systems, packaging machinery, material handling equipment, and manufacturing automation lines where moderate power requirements exist. Deploy the 1756-PA50 in smaller ControlLogix configurations with up to 4-6 I/O modules, or use it as a dedicated supply for critical control modules requiring isolated power.

System Integration Solutions

Pair the 1756-PA50 with ControlLogix processors (1756-L6x series), digital I/O modules, and analog input cards for complete automation solutions. For higher power demands, consider upgrading to the Allen-Bradley 1756-PA75 75W AC Power Supply. When DC input is preferred, explore the 1756-PB50 DC Power Supply alternative. Monitor power health proactively with the 1756-PBM Power Supply Monitor.

Common Questions Answered

Q: Can I use this with 1756 redundant configurations?
A: The 1756-PA50 is designed for standard (non-redundant) applications. For redundant power architectures, select the 1756-PA75R redundant model.

Q: What's the maximum current draw per voltage rail?
A: The +5V rail supplies up to 10A, while the +24V rail provides up to 2A, totaling 50W combined output.

Q: Does it support hot-swap installation?
A: No, power must be removed from the chassis before installing or removing this supply to prevent damage.
