The SLC 500 family is a growing family of small programmable controllers built around two hardware options: a fixed controller or a modular controller. The modular controller offers you maximum flexibility in system configuration. Wth its multiple processor choices, numerous power supply options and extensive I/O capacity, the modular SLC 500 controller allows you to create a system specifically designed for your application.
The fixed controller provides the power supply, inputs and outputs, and processor in one unit. It also offers a 2-slot expansion chassis for increased flexibility. The programming tools and most I/O modules are compatible between the two hardware options, so you can cost effectively solve a broad range of applications.
