Information About BK9050
The BK9050 is part of Beckhoff’s BK series of Ethernet bus couplers, designed for efficient integration of modular I/O terminals into Ethernet-based automation systems. Supporting up to 64 terminals and expandable to 255, it provides extensive digital and analog signal handling with up to 512 bytes each for input and output data. With built-in protocol support for TwinCAT ADS, Modbus TCP, and Beckhoff real-time Ethernet, the coupler ensures versatile communication options for industrial networks. Compact, DIN rail mountable, and equipped with IP20 protection, the BK9050 is well-suited for distributed control architectures in factory automation.
Key Features:
-
Ethernet TCP/IP Connectivity: Provides seamless integration of Beckhoff bus terminals into Ethernet-based fieldbus networks.
-
High Data Capacity: Supports up to 512 input bytes and 512 output bytes for handling large volumes of I/O signals.
-
Expandable Terminal Support: Connects 64 terminals natively, expandable to 255 using K-bus extension technology.
-
Multi-Protocol Support: Compatible with TwinCAT ADS, Modbus TCP, and Beckhoff real-time Ethernet for flexible communication.
-
Robust Power Handling: Offers 24 V DC supply with 1750 mA K-bus current and 10 A power contacts for demanding loads.
-
Reliable Electrical Isolation: Provides 500 V separation between fieldbus, supply voltage, and power contacts for safety.
-
Compact DIN Rail Mounting: Slim 44 mm polycarbonate housing allows easy installation in modular control panels.
-
Industrial-Grade Operation: Operates from 0 to +55 °C, with EMC, vibration, and shock resistance for harsh environments.
The BK9050 delivers the reliability and precision required for Ethernet-based fieldbus communication and modular I/O integration in industrial automation systems.
