Designed for use with Allen-Bradley SLC 500 controllers, it communicates via the backplane to deliver real-time counts and status to the CPU, enabling high-speed counting and encoder interfacing for motion-related applications. The module draws power directly from the backplane, typically around 200 mA at 5 V, so no external power supply is required for its internal logic. Installation involves placing the 1746-HT in a 1746 rack slot and connecting encoder or pulse input signals to the module’s inputs, where the PLC can access the resulting counts through standard SLC 500 backplane communication. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658981310766,"sku":null,"price":580.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_271ac4eb-5171-4b74-8294-88e78f878c10.jpg?v=1769526278","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-ht-programmable-logic-controller-module","provider":"PLG Automation ","version":"1.0","type":"link"}
