It powers two ASi networks from a single supply and includes two ASi‑3 Masters for robust fieldbus connectivity. The unit offers 6 digital inputs or 3 × 2‑channel safe inputs (SIL 3, CAT 4), expandable to 62 two‑channel safe inputs in a single configuration and up to 1,922 two‑channel safe inputs in a max configuration; on the output side it provides 6 safe outputs (electronic releases), expandable to 32 safe outputs. A Safe Link plus a dedicated Ethernet\/IP + Modbus TCP diagnostic interface enable straightforward configuration, duplicate address recognition, and ASi fault detection, with optional C programming for customization. Designed for IP20 protection, the BWU2821 integrates with existing control architectures to monitor and control ASi devices over standard Ethernet networks while preserving safety monitoring.\u003c\/p\u003e\u003c\/div\u003e","brand":"BIHL","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676964585774,"sku":null,"price":441.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_9bd5835f-0d2d-436c-a9ac-b53b17dcb6c1.jpg?v=1769555863","url":"https:\/\/plgautomation.com\/products\/bihl-wiedemann-bwu2821-modbus-tcp-gateway-module","provider":"PLG Automation ","version":"1.0","type":"link"}
