As part of the 1745-E expansion family, the 1745-E105 is designed to attach to a compatible SLC 100 CPU\/backplane to provide additional input\/output points for small automation tasks. The module carries a maximum power requirement of 12 VA, a specification common to the E101, E102, E103, E105, and E106 expansion units, enabling engineers to budget power in compact control panels. Typical applications include retrofits or new-builds that rely on the SLC 100 for straightforward control loops, where a compact, economical expansion option is desirable. The 1745-E105 is not a standalone controller; it relies on a compatible SLC 100 base unit to operate and interface with its backplane, I\/O wiring, and programming environment. In practice, it supports simple expansion scenarios where additional I\/O is needed without migrating to newer PLC platforms. When pairing with a base SLC 100 system, verify compatibility of firmware and I\/O modules to ensure proper communication and backplane interfacing.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657358901550,"sku":null,"price":90.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_a0dc7c37-b154-4bdd-9619-e13efbbc6cce.jpg?v=1769468212","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1745-e105-programmable-logic-controller","provider":"PLG Automation ","version":"1.0","type":"link"}
