Allen Bradley SLC 500 Controller Family

Core Performance & Industrial Application

The Allen-Bradley SLC 500 is a chassis-based modular programmable controller family for small-to-medium machine and process control.

It combines a modular processor (SLC 5/01 to 5/05), power supply, backplane chassis and discrete/analog/specialty I/O modules.

Processor memory ranges from 1K to 64K and the system supports up to 4096 input and 4096 output points with local and remote I/O expansion.

Built-in RS-232/422/423 serial port; selected processors add DH+, Universal Remote I/O, DeviceNet and ControlNet communication.

Programming and configuration use RSLogix 500 ladder logic with advanced file handling, sequencer, diagnostic and shift-register instructions.

It is a widely kept legacy spare family for packaging, material handling and machine control retrofit.
