Beckhoff BK9000 – Overview The Beckhoff BK9000 is a compact bus coupler that connects a modular terminal block system to a standard Ethernet TCP/IP network. It supports data rates of 10 Mbit/s and 100 Mbit/s, and handles automatic process-image mapping for up to 64 bus terminals, expandable to 255 using the K-bus extension.This module simplifies the integration of I/O modules into Ethernet-based automation systems. Key Features Ethernet TCP/IP support at 10/100 Mbit/s Connects up to 64 bus terminals (expandable to 255) Automatic assignment of input/output words into process image Supports protocols such as ADS (TwinCAT) and Modbus TCP Standard RJ45 Ethernet interface 24 V DC power supply Compact DIN-rail mountable design with IP20 protection Electrical isolation for robust industrial application Technical Specifications Part Numbers: – BK9000 – BK 9000 Supported Bus Terminals: 64 (255 with K-bus extension) Max Process Image Size: 512 bytes input + 512 bytes output Digital Peripheral Signals: 512 inputs/outputs Analog Peripheral Signals: 128 inputs/outputs Data Rates: 10/100 Mbit/s (automatic detection) Bus Interface: 1 × RJ45 Ethernet Power Supply: 24 V DC (-15% / +20%) Current Consumption: ~70 mA + K-bus current /4, up to ~500 mA max K-bus Supply Capacity: 1750 mA Power Contacts (optional): 24 V DC / max. 10 A Electrical Isolation: 500 V (power contact/supply/fieldbus) Operating Temperature: –25 °C … +60 °C Storage Temperature: –40 °C … +85 °C Protection Rating: IP20 Weight: Approx. 0.17 kg Dimensions (W × H × D): Approx. 51 mm × 100 mm × 69 mm Manufacturer: Beckhoff Automation Weight: 0.10 – 0.23 kg (0.22 – 0.50 lb)Packed dimensions: 12 × 7 × 6 cm (4.7 × 2.8 × 2.4 in) Applications Integration of modular terminal blocks with Ethernet networks in industrial automation Control cabinets where large numbers of I/O modules need Ethernet connectivity Systems requiring high-speed data communication and modular expansion Automation setups using standard Ethernet for I/O station connection Why Choose Beckhoff BK9000 Enables seamless Ethernet connectivity for terminal block systems Supports modular expansion with large I/O count and process image mapping Robust industrial design with wide temperature range and electrical isolation Simple installation and configuration for Ethernet-based automation Order Now The Beckhoff BK9000 Ethernet TCP/IP Bus Coupler is available for order and ships worldwide.
