The LP103 variant supports a total of 16 I\/O points: ten discrete inputs and six discrete outputs, suitable for compact machine control tasks. It uses battery-backed CMOS RAM to store the ladder logic program, with a documented memory of 885 words, and provides an EEPROM memory module interface for program loading and data storage. A built-in expansion unit connection port enables attaching compatible 1745 expansion modules to extend I\/O as needed. User interaction is facilitated by an Auto\/Manual control switch and diagnostic LEDs, along with battery compartment and I\/O status indicators for quick health checks. The unit supports AC input voltage configurations on its I\/O lines, with input voltage options in the 85–132 VAC or 170–265 VAC ranges, aligning with the legacy SLC 100’s broad voltage tolerance. The LP103 is explicitly marketed as a 1745-LP103 Processor Unit for SLC 100 and, like other LP variants, is designed to operate within a fixed I\/O base, without plug-in 1746-style I\/O modules. This model is discontinued by the manufacturer, reflecting its retirement from current production while still commonly found in legacy automation and machine retrofits.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51658992746798,"sku":null,"price":94.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_fb1aed70-a925-461f-b34a-70b045093760.jpg?v=1769526353","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1745-lp103-programmable-logic-controller-processor-unit","provider":"PLG Automation ","version":"1.0","type":"link"}
