Each input channel is designed for 120 VAC operation and presents a nominal input current of about 11 mA, while the outputs are AC-rated with an operating voltage range of 20 to 132 VAC, suitable for switching line‑voltage devices such as relays and contactors. The 1791-8AC mounts directly to a compatible Allen‑Bradley controller as a Block I\/O device and supports both horizontal and vertical mounting to fit various panel layouts. As a 16-point block, it provides a straightforward means to expand discrete control for AC field devices within classic Allen‑Bradley control architectures, delivering reliable direct I\/O connection without intermediate adapters. The model is commonly identified as 1791-8AC, with eight inputs and eight outputs, 16 total points, configured for 120 VAC operation. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46279532019946,"sku":null,"price":601.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-077.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1791-8ac-block-i-o-digital-module","provider":"GTG Hardware","version":"1.0","type":"link"}
