Product Overview
The Allen-Bradley 1769-PA4 is a Compact I/O AC input power supply manufactured by Rockwell Automation for supported CompactLogix and Bulletin 1769 I/O systems. It provides electrical power to compatible modules through the system backplane. The power supply is designed for a 120/240V AC input class and provides switch-selectable operating voltage ranges of 85–265V AC or 170–265V AC, with an input frequency of 47–63Hz. The correct voltage selection and input wiring must be confirmed before energizing the equipment. The 1769-PA4 delivers a manufacturer-specified backplane current capacity of 4.0A at 5V DC and 2.0A at 24V DC. These ratings describe the available I/O system bus current and must not be confused with independent general-purpose field power outputs. The unit supports the installation of compatible 1769 Compact I/O modules to either side of the power supply. Rockwell Automation allows up to eight modules per side, subject to the controller's overall I/O module capacity, individual module power supply distance ratings and available power budget. The device features a compact open-style enclosure with DIN rail or panel mounting. Its approximate dimensions are 118 x 70 x 87mm, and its approximate weight is 630g. The manufacturer specifies 18W power dissipation at 60°C and an operating temperature range of 0–60°C. Rockwell Automation currently classifies catalog number 1769-PA4 as Active Mature. The supplied actual photograph shows an Allen-Bradley carton marked 1769-PA4, Series A, and POWER SUPPLY 120/240VAC INPUT. The packaging carries a date of 2024/11/05, the marking PRODUCT OF MALAYSIA, and a visible FACTORY SEAL label. The photograph confirms the catalog number printed on the carton. The power supply module's physical nameplate, internal condition, and electrical operating performance have not been independently verified. Please confirm the exact module, input supply, system power requirements and included accessories before ordering.
