Product Description:

The Beckhoff BK9103-1006 is a versatile bus coupler from the BK EtherCAT Bus Coupler Series, designed to handle a wide range of automation tasks. It supports up to 64 bus terminals, with the possibility to extend this number to 255 terminals using a K-bus extension. This makes it scalable for larger systems that require more input/output options. The bus coupler allows for 512 digital peripheral signals for inputs and outputs, while also supporting up to 256 analog peripheral signals, providing flexibility for various control and monitoring needs.

The BK9103-1006 operates using the PROFINET RT (Class B) protocol, enabling real-time communication for automation processes. It supports data transfer rates of 10/100 Mbit/s, with automatic recognition of the transmission rate, ensuring efficient and reliable communication. The device uses two RJ45 bus interfaces with a 2-channel switch, supporting line or star topologies, allowing for flexible network setups.

The KS2000 configuration software provides a simple and flexible way to configure the BK9103-1006, enabling users to easily set up the device according to their system requirements. The device operates with a 24 V DC power supply, with an input current of 70 mA plus the K-bus current, and a maximum input current of 500 mA. It also supports a current supply of 1750 mA for the K-bus, ensuring sufficient power for connected terminals. The power contacts can handle 24 V DC and 10 A, making it suitable for powering other connected devices. Weighing approximately 170 grams, the BK9103-1006 is compact and protected by an IP20 rating, making it suitable for installation in controlled environments. Its 4 x 2 twisted pair copper cable data transfer medium ensures reliable communication, with support for category 3 cables (10 Mbit/s) and category 5 cables (100 Mbit/s).
