Balluff BNI IOL-104-000-K021 IO-Link sensor/actuator hub Part number BNI0021

This IO-Link hub provides an M12 master connection alongside eight M8 sensor/actuator ports, allowing multiple field devices to be consolidated onto a single IO-Link line. The housing is constructed from GF/PBT with an FKM gasket, and it achieves an IP67 rating when properly threaded in, suiting installation directly on machine structures or panel exteriors. It operates from an 18 to 30.2 VDC supply, rated at 24 V, and mounts via a two-hole screw fixing. Typical use is in decentralised field wiring architectures where sensor and actuator signals are gathered close to the point of use before being passed back to a controller over IO-Link.
