1769 I/O Power Supplies
Each 1769-L3x controller and additional bank of I/O modules requires a 1769 power supply. Place 1769 I/O modules to the left or the right of the 1769 power supply. As many as eight I/O modules can be placed on each side of the power supply.
Each 1769 module also has a power supply distance rating (the number of modules from the power supply). Each module must be located within its distance rating. See the specifications for the module to determine its distance rating.
