The SLC 500 comes in two different styles: modular and fixed. These styles
are shown below. The modular controller consists of a rack, power supply,
processor (CPU), and Input/Output (I/O) modules. The fixed controller
consists of a power supply, processor (CPU), and a fixed number of I/O
contained in a single unit. You can add an expansion rack to the fixed
controller.
