Allen-Bradley 1747-L524BE SLC-500 PLC Processor

The Allen-Bradley 1747-L524BE SLC-500 PLC Processor is a SLC 5/02 CPU that provides a compact 4K-memory controller for backplane-based SLC-500 racks, ideal for small- to mid-size automation tasks. As a Series B/C L524 variant, it is key-switchless; mode changes (Program, Run, Remote) are commanded through RSLogix 500 over the DH-485 network using a 1747-PIC interface or an AIC+ adapter (1761-NET-AIC). The processor supports DH-485 communications and connects with standard SLC-500 I/O racks for discrete control and simple networking, delivering reliable execution for ladder logic and timer/counting routines in automation projects. Programming and configuration are performed with RSLogix 500, making this CPU a straightforward choice for existing SLC-500 environments that require a compact, easy-to-integrate controller.
