Bihl+Wiedemann BWU1280-11081 AS-i Coupler Module

BWU1280-11081 is the Bihl+Wiedemann AS‑i/AS‑i Coupler Module that bridges two AS‑i networks in a rugged, IP65‑rated package. It houses two independent internal 4I/4O AS‑i nodes, delivering four inputs and four outputs per node so you can segment a control system without extra gateways while maintaining the familiar AS‑i topology. Designed for harsh industrial environments, the BWU1280 enables reliable field communication and straightforward diagnostics across both networks, with built‑in indicators to monitor activity and fault status. This dual‑network coupler fits neatly into machine bays, control cabinets, or directly on equipment used in packaging lines, conveyors, and automated cells, simplifying expansion and maintenance by consolidating interconnection points in a single device. As part of the Bihl+Wiedemann AS‑i family, the BWU1280‑11081 integrates with the company’s broader ecosystem of masters, IO modules, and configuration tools, supporting seamless commissioning, IO mapping, and ongoing network visibility. In practical terms, this module is ideal when a system requires interconnection or isolation of two AS‑i networks without sacrificing the ease of use and diagnostic clarity that AS‑i provides, all within a compact, rugged enclosure.
