CompactLogix Power Supplies
Bulletin 1768 CompactLogix™ Power Supplies and Bulletin 1769 Compact I/O™ Expansion Power Supplies help keep your system running smoothly. Select power supplies based on the controller and the number of additional I/O banks you're using. Packaged controllers (1769-L23x, 1769-L16, 1769-L18, 1769-L24, 1769-L27) do not require power supplies because each controller package includes an integrated power supply.
