Weidmüller SAI-AU M8 SB 8DI 1938600000 Bus Module

The Weidmüller SAI-AU M8 SB 8DI 1938600000 Bus Module is a compact distributed I/O sensor bus interface that brings eight digital inputs into PLC-based automation networks, enabling reliable field-level sensor connectivity for machines, conveyors, and process equipment. Designed for factory automation panels, it uses eight DI over M8 sensor connections and supports field-level signal distribution and monitoring across distributed I/O signals. Key specs include eight digital inputs (8 DI), M8 sensor connectors, and an interface type described as a Distributed I/O sensor bus module, with mounting suitable for industrial machines and panels and an installation environment focused on factory automation and process control systems. The module is intended to connect and manage multiple digital input signals within industrial automation and control systems, making it suitable for sensor network integration, automation expansion, and distributed I/O retrofits in PLC-controlled machinery, robotic systems, packaging lines, material handling, and process manufacturing installations. Common replacements listed include Phoenix Contact I/O Bus Module, Siemens Distributed I/O Module, and Allen-Bradley POINT I/O Module.
