Balluff BNI EIP-502-105-Z015 Network Interface Module

The Balluff BNI EIP-502-105-Z015 Network Interface Module is a decentralized IO-Link master that bridges IO-Link devices to an EtherNet/IP network, enabling distributed I/O in automation systems. This 16-in/16-out IO-Link Master runs from a DC supply and exposes 16 digital inputs and 16 digital outputs, making it suitable for sensors and actuators across a factory floor. The unit’s compact enclosure measures 68 mm wide by 37.9 mm high by 224 mm deep and carries an IP67 protection rating for robust operation in harsh environments. Balluff positions this device as part of the BNI EIP line (BNI004A Master IO-Link), and Omron's NJ/NX-series EtherNet/IP connection guide lists the BNI EIP-502-105-Z015 among applicable devices, illustrating cross‑vendor integration on EtherNet/IP networks.
