(1) You can use a maximum of two banks of I/O modules. This condition occurs when configuring your system with a MicroLogix 1500 controller, one
expansion cable, one expansion power supply, and a total of eight I/O modules. The expansion power supply cannot be directly connected to the
MicroLogix 1500 controller.
