Bihl+Wiedemann BWU2546 ASI-3 Profibus Gateway

The BWU2546 ASi-3 PROFIBUS Gateway is a stainless steel, 2‑master gateway that bridges ASi‑3 devices to PROFIBUS DP networks, enabling ASi nodes to be controlled from a PROFIBUS master. It provides two ASi‑3 master interfaces, each capable of delivering up to 4 A per ASi circuit, with integrated decoupling coils and ASi current measurement in the gateway, plus diagnostic and configuration access via an Ethernet diagnostic interface, including duplicate address recognition and an ASi fault detector. Programming in C is optional, and the unit is IP20 rated; it can be powered from standard 24 V supplies, with the manufacturer noting cost‑effective 30 V options and the option to consider Ethernet‑based interfaces for new installations (e.g., Profinet via BWU3852).
