The Allen-Bradley SLC 500 is a small, chassis-based, modular family of programmable controllers and I/O. The SLCs smaller size means you can use an SLC in applications where you can’t afford the size and overhead of a traditional, full-sized PLC. With its multiple processor choices, numerous power supply options and extensive I/O capacity, the SLC 500 controller allows the creation of a system designed for a given application. — Rockwell Automation, Milwaukee, Wisc.
