Product Description P/N: BK9105
Description
The Beckhoff BK9105 is an EtherNet/IP bus coupler designed to interface modular Beckhoff I/O terminals with industrial Ethernet networks. Supporting 10/100 Mbps communication through dual RJ45 ports, it automatically identifies connected terminals and maps their signals to the controller’s process image. Operating on 24 VDC, the unit supports up to 64 terminals—or 255 with K-bus extension—for flexible system expansion.

Information About BK9105
The BK9105 integrates EtherNet/IP connectivity into Beckhoff’s modular terminal system, enabling seamless communication between EtherNet/IP controllers and distributed I/O modules. The coupler auto-recognizes up to 64 standard terminals, assigning their inputs and outputs directly to fieldbus process data, while an extension option increases this capacity to 255 terminals.
Its built-in 2-port RJ45 switch supports both line and star wiring topologies, allowing cost-efficient station chaining with up to 20 couplers or a 2 km total line length. DIP switch configuration enables fixed IP addressing, while DHCP support provides automatic address assignment when required.
Engineered for industrial environments, the BK9105 includes galvanic isolation, comprehensive EMC compliance, shock/vibration resistance, and IP20 protection. With a robust electrical design—24 VDC supply, 1.75 A K-bus current, and support for up to 3,936 digital or 122 analog signals—it offers scalable and reliable EtherNet/IP integration for automation systems.
Key Features:
- EtherNet/IP connectivity: ODVA-compliant and designed for Industrial Ethernet applications.
- Supports up to 64 terminals: Expandable to 255 via K-bus extension.
- Auto-recognition of terminals: Automatically maps all connected I/O to the process image.
- Dual RJ45 ports: Enables line or star topology with integrated 2-channel switch functionality.
- 10/100 Mbps communication: Auto-negotiation for seamless network integration.
- DIP switch addressing: Allows manual IP settings; DHCP supported for automatic assignment.
- Industrial-grade design: EN/IEC-certified for EMC, shock, vibration, and hazardous environments (ATEX/IECEx).
- Long-distance cascading: Chain up to 20 couplers with up to 2 km total line length.
The BK9105 delivers the reliability and precision required for EtherNet/IP-based distributed I/O architectures.
