Bihl+Wiedemann BWU2645 ASI Digital IO Module IP67

The BWU2645 ASi Digital I/O Module from Bihl+Wiedemann is a rugged IP67-rated slave for AS-Interface networks, built to operate in harsh environments where washdowns and dust exposure are common. It provides four digital inputs and four digital outputs (4I/4O) via M12 field connectors, enabling compact, field-level sensing and actuation on a single ASi node. The module supports flexible ASi addressing options, including AB-address configurations, single-address setups, or ASi-5 addressing, which helps with scalable installations and future upgrades. Its IP67 enclosure protects the electronics from immersion and contaminants, making it suitable for outdoor installations, machinery on production lines, or equipment housed in challenging environments. Designed to integrate directly into an ASi master network, the BWU2645 delivers reliable digital input signals and drive outputs for straightforward automation tasks without the need for separate PLC I/O cards. This module is part of Bihl+Wiedemann’s digital I/O family for ASi, offering a compact, robust solution for monitoring sensors and controlling actuators in demanding industrial settings, while maintaining straightforward wiring and robust field installation.
