As part of the SLC-100 expansion family, it is designed to connect to a SLC-100 processor unit to extend the controller’s I\/O for machine-control and process applications. In catalogs it is commonly listed as a BASIC EXPANSION UNIT (1745-E104B) in some listings. The outputs are relay-based, enabling connection to external circuits, while the inputs accept standard discrete signals from sensors and switches. This expansion module is associated with the older 1745 SLC-100 family and is used to scale I\/O in legacy manufacturing and automation installations. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657318727982,"sku":null,"price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_04e61662-f540-4e4f-b9f4-8b0e1936560d.jpg?v=1769467761","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1745-e104-programmable-expansion-unit","provider":"PLG Automation ","version":"1.0","type":"link"}
