Product Description:
The BK3150-0018 Bus Coupler of Beckhoff is designed for efficient industrial connections. It is part of the BK EtherCAT Bus Couplers series. The coupler is known for offering dependable performance in industrial control applications.
The BK3150-0018 bus coupler internal power supply line that distributes power to I/O modules can handle up to 24 volts DC. It connects to the fieldbus (EtherCAT in this case) using a standard 9-pin D-sub connector, which is shielded to reduce interference. It comes with a dielectric strength of 500 volts which makes it to withstand up to 500 V by protecting the system from electrical faults and crosstalk. The module communication speed can go up to 12 million bits per second, with automatic detection of the correct speed. It is featured with an external fuse which protects the 24 V power line. It is just about 100 grams which makes it easy to mount or integrate into compact control cabinets. The coupler is able to be installed in any orientation which gives flexibility in cabinet layout. The module briefly draws 2.5 times its normal current at startup.
The BK3150-0018 bus coupler meets European standards for electromagnetic compatibility. Its power contact line that feeds the I/O terminals can carry up to 10 amps. The coupler is tested to withstand industrial-level vibrations and shocks and you can connect up to 256 digital I/O signals (combined input/output) using a specific coupler version. All of its internal circuits are isolated to prevent interference or damage across the power, logic and communication areas. It is featured with 128 inputs/outputs (BK3x00) of analog peripheral signals which means it can be connected with 128 analog I/O channels.
Frequently Asked Questions about BK3150-0018:
Q: Why does the BK3150-0018 Bus Coupler use a 9-pin D-sub connector for EtherCAT?
A: The 9-pin D-sub ensures stable communication and shielding against electrical noise in harsh industrial environments. It also simplifies standard-compliant cabling.
Q: How does dielectric strength of 500 V benefit the BK3150-0018 Bus Coupler in control cabinets?
A: It enhances system safety by preventing voltage spikes from affecting communication or power lines. This is vital in installations with mixed power and signal routing.
Q: Why is automatic baud rate detection important in the BK3150-0018 Bus Coupler?
A: It simplifies setup by adapting to network speed without manual configuration. This ensures faster commissioning and minimizes errors during installation.
Q: How does startup current of 2.5 times continuous current impact system design for BK3150-0018?
A: It requires power supplies and circuit protection to be sized accordingly. This prevents tripping during initial energization or restarts.
Q: Why is the BK3150-0018 capable of variable installation orientation?
A: It allows flexible integration in tight spaces and varied cabinet layouts. This makes it ideal for decentralized or compact automation systems.
