The Allen-Bradley 1747-L511, also cataloged as the SLC5/01 SLC 5/01 Controller, operates as a dedicated CPU module for sequential logic execution within SLC 500 programmable controller platforms. The controller provides processor functions, user memory storage, and control program execution through the SLC backplane interface.

Model Configuration Details

The 1747-L511 is an SLC 5/01 CPU module with 1 K RAM memory capacity. This model belongs to the first generation of SLC 500 processors and provides basic processor execution functions without additional communication features listed in the supplied specifications.

Hardware Specifications

Industrial Control Platform Characteristics

The SLC 5/01 processor uses the SLC 500 backplane architecture for communication between the CPU module and installed I/O modules. The controller firmware executes ladder logic programs stored in internal RAM memory.

The processor is designed for basic PLC control tasks where compact CPU execution and SLC 500 I/O integration are required. Backplane communication provides module data exchange and processor access to connected SLC 500 system components.
