Allen-Bradley 1747-L524 Programmable Logic Controller

Allen-Bradley 1747-L524 SLC 5/02 Processor is a modular CPU for the SLC 500 family designed to live in an SLC 500 rack backplane. It provides 4 KB of user memory for ladder logic, data tables, and subroutines, supporting compact control programs for small automation tasks. The processor includes DH+ communication for I/O networks and a serial RS-232 port for programming and diagnostics, with common PC connections via cables such as 1747-PIC, 1747-CP3, or 1747-UIC. As a Series B/C 5/02 processor, it is intended for reliable, straightforward control in standalone machines or small automation cells. The module is chassis-mountable in compatible Allen-Bradley SLC 500 racks and coordinates logic, timing, and data exchange across the backplane with I/O modules, making it a classic solution for mid- to low-complexity industrial control tasks that favor rugged, field-proven hardware.
