Input Power and DC Output
The 1769-PA4 accepts AC input power and supplies DC power to supported CompactLogix system components. Its rated output currents differ by voltage rail: 4 A at 5 VDC and 2 A at 24 VDC. When planning a system, verify that the combined module load remains within the power supply’s applicable output ratings.
The specified power consumption varies with the input condition. The maximum inrush current of 25 A at 132 V AC is relevant when assessing power-up current and upstream protective device selection.
Mounting and Installation
The module supports both DIN rail and panel mounting. Before installation, verify the required mounting arrangement, AC input configuration, and power requirements against the equipment documentation. Also confirm that the connected system load falls within the power supply’s rated capacity.
