Controller Styles
The SLC 500 comes in two different styles: modular and fixed. These styles are
illustrated below. The modular controller consists of a chassis, 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. An expansion chassis can be added to the fixed controller.
