The Allen-Bradley SLC 500 is a small chassis-based family of programmable controllers, discrete, analogue, and speciality I/O, and peripheral devices. The SLC 500 family delivers power and flexibility with a wide range of communication configurations, features, and memory options. The RSLogix 500 ladder logic programming package provides flexible editors, point-and-click I/O configuration, and a powerful database editor, as well as diagnostic and troubleshooting tools to help you save project development time and maximize productivity.

With up to 64 K of configurable data/program memory available and over 60 types of I/O modules, as well as a choice of networking options, the SLC system provides a powerful solution for stand-alone or distributed industrial control.

• Powerful, yet affordable – SLC 500 programmable controllers provide excellent value with extensive capabilities to address a broad range of applications including material handling, HVAC control, high-speed assembly operations, small process control, simple motion control, and SCADA.
• Modularity – Modular processes, power supplies, I/O, memory options, and communication interfaces allow for a configurable and expandable system. You can configure your system for the number of I/O, the amount of memory, and the communication networks needed. Later, you can expand the system by adding I/O, memory, or communication interfaces.
• Advanced instruction set – Includes indirect addressing, high-level math
capability, and computer instruction. Communication network versatility - Choose from onboard Ethernet, DH+, or DH-485, as well as options for
ControlNet, DeviceNet, or Remote I/O communications.
