Industrial BNI0091 IO-Link Sensor Actuator Hub

The Balluff BNI0091 IO-Link sensor/actuator hub is a decentralized IO-Link 1.1 I/O module that bundles 16 digital inputs and 16 digital outputs for connection to an IO-Link master, enabling scalable, dense signal distribution in automation systems. It consolidates field devices through eight M12 female, 5‑pole, A‑coded connection slots and includes an extension port for expansion, all housed in PPS with an IP67 rating and a operating temperature range of -5 to 70 °C. The unit is powered from 18 to 30.2 V DC and supports a maximum output current of 2 A. Its compact dimensions are 68 × 36.8 × 183.5 mm. The hub uses IO-Link 1.1 communication and provides 16 digital inputs (PNP, Type 3) and 16 digital outputs (PNP), enabling direct integration of discrete sensors and actuators to a Balluff IO-Link master. Common applications include consolidating sensor signals and driving actuators across manufacturing lines, robotics cells, and packaging equipment where a single IO-Link master can manage multiple devices via one hub.
