It provides 4 KB of program memory and is part of the SLC 5\/01 family, suitable for small-scale discrete or batch processes with straightforward control logic. The CPU integrates RS-232 communication (DF1\/ASCII) and DH-485 networking, enabling device-to-controller communications and integration with standard SLC 500 I\/O backplanes. Optional expansion memory is available via 1747-M1 (1 KB EEPROM) and 1747-M2 (4 KB EEPROM) to extend non-volatile storage for programs and data. In operation, it interfaces with compatible 1746\/1747 I\/O chassis and backplanes to execute ladder logic, timers, and counters. Common applications include simple material handling, packaging line control, and basic process sequencing where a compact, reliable PLC is appropriate. The L514 model delivers a compact footprint and a familiar SLC 500 programming model compatible with RSLogix 500, making it suitable for legacy systems that require easy maintenance and long-term parts availability.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658960896302,"sku":null,"price":217.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_1f3701be-8d62-43f9-81ec-e93aa8f7ac7c.jpg?v=1769526012","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-l514-cpu-processor-unit-slc-5-05","provider":"PLG Automation ","version":"1.0","type":"link"}
