Product Description

The Beckhoff BK9103-1005 is a bus coupler from the BK EtherCAT Bus Coupler Series, designed for use in industrial automation systems. This device is capable of supporting up to 64 bus terminals, which can be extended to 255 terminals with a K-bus extension, offering flexibility and scalability for larger applications. The bus coupler supports 512 bytes of input and 512 bytes of output on the fieldbus, allowing it to handle high volumes of data in real-time operations.

The BK9103-1005 can manage 512 digital peripheral input/output signals and supports 256 analog peripheral signals for inputs and outputs. These capabilities make it suitable for various automation tasks, from controlling digital I/O devices to handling analog data from sensors and actuators. The device operates using the PROFINET RT (Class B) protocol, which ensures fast and reliable communication in real-time applications, making it ideal for time-critical processes in industrial environments.

Configuration is done via the KS2000 software, providing a straightforward setup and customization process. The device offers 10/100 Mbit/s data transfer rates with automatic recognition of the transmission rate. It uses two RJ45 bus interfaces for communication, supporting line or star wiring topologies, which adds flexibility in network design. The data transfer medium includes 4 x 2 twisted pair copper cables, with support for category 3 cables (10 Mbit/s) and category 5 cables (100 Mbit/s). In terms of power, the BK9103-1005 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. The K-bus current supply is rated at 1750 mA, ensuring sufficient power for connected terminals. The starting current is approximately 2.5 times the continuous current, and the device uses a recommended fuse of ≤ 10 A.
