The Allen-Bradley 1747-L524 is a SLC 500 Series 5/02 processor module used in Rockwell Automation's SLC 500 racks. It is available in memory configurations: Series A 1747-L524/A with 1K of user memory, and Series B/C 1747-L524/B or -C with 4K of user memory. This keyless CPU ships without a front-panel keyswitch; mode changes (Program, Run, Remote) are commanded over the DH-485 network via RSLogix 500 using a 1747-PIC interface or a 1761-NET-AIC. Common uses include automating small to mid-sized industrial processes where a compact CPU with DH-485 communication fits the rack.
