Product Overview
The 1768-PA3/A is an Allen-Bradley CompactLogix L4x AC/DC input power supply module. It supplies 24 V DC aux power to CompactLogix L4x controllers and associated I/O modules. It supports 85-265 V AC or 108-132 V DC input and delivers up to 3.5 A at 24 V DC per the CompactLogix L4x architecture. Typically used in CompactLogix control systems for factory or machine-level installation requiring consistent auxiliary DC power. Part number 1768-PA3/A integrates with L4x platform controllers and is now discontinued, replaced by later models.
