It accepts DC input signals from 10 to 60 V and uses True High sensing, converting external digital signals into a logic-level input for the connected controller. The module provides eight inputs, arranged as two points per common terminal, enabling compact wiring within standard Modicon 800 Series I\/O racks. Designed to monitor positive-logic devices such as pushbuttons, limit switches, and proximity sensors, the AS-B821-108 serves as a scalable way to expand a control system’s input capability without changing the main controller. Integrated into Schneider Electric’s Modicon ecosystem, this 800 Series I\/O module complements other discrete I\/O options to support automation tasks across manufacturing lines, packaging systems, and material-handling equipment that rely on reliable, DC-driven digital inputs.\u003c\/p\u003e\u003c\/div\u003e","brand":"SCHNEIDER","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46283702206698,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-021.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/schneider-electric-as-b821-108-plc-module","provider":"GTG Hardware","version":"1.0","type":"link"}
