Balluff BNI004F EtherNet IP Network Block

Balluff's BNI004F EtherNet/IP Network Block, also documented as BNI EIP-302-105-Z015, is a rugged Ethernet/IP IO block that provides 16 digital inputs for direct sensor and switch signaling on industrial networks. It features a single Ethernet/IP interface (1 x 10BASE-T/100BASE-TX) to connect to EtherNet/IP networks and controllers, enabling straightforward integration into automation systems. The block is built for harsh environments with an IP67-rated enclosure and a compact footprint measuring about 68 × 37.9 × 224 mm, designed for mounting alongside other IO modules in equipment racks or on machine enclosures. Ordering code BNI004F identifies this specific Balluff model within the BNI EIP-302-105-Z015 family. Typical applications include expanding the digital input capability of a control system in manufacturing lines, packaging equipment, conveyors, and other automated machinery where reliable EtherNet/IP communication and robust protection are required. By delivering a dedicated set of 16 input channels over EtherNet/IP, the BNI004F allows a controller to monitor multiple field devices—such as limit switches, proximity sensors, and other digital sensors—over a standard industrial Ethernet backbone without adding complex wiring or separate I/O cabinets. This makes it a compact solution for scalable, module-based input expansion in modern control architectures that rely on EtherNet/IP for fieldbus communication.
