Designed for distributed machine-mount installations, the IP2311-B400 fieldbus box facilitates direct, cabinet-free connection of digital signals in rugged industrial environments. This compact I/O module integrates 4 digital inputs and 4 digital outputs, routing them through standard M8 screw-type connectors for secure wiring to local sensors and actuators. Operating at data transfer rates up to 500 kBaud, the unit handles communications over distances up to 400 meters between modules using specialized LiYCY cabling. The fieldbus interface is established via robust 9-pin M23 connectors, allowing reliable integration into decentralized control architectures. System configuration and diagnostics can be performed seamlessly using the KS2000 software interface.
