Product Description:

The BK2010 Series fieldbus coupler is made for adding more digital I/O modules in industrial automation. In order to guarantee the system's functionality and the stability of data transmission, Beckhoff implements durable fiber optic connection technology.

The BK2010 fieldbus coupler can connect to a fieldbus process picture that has 32 bytes heading in and 32 bytes going out. I/O modules and controllers can easily share info this way. Data can be sent at a rate of 2.5M when 10 units with 32-bit I/O are used. This means that the coupler takes about 0.26 ms to send data. Both BK2010 plastic and Z1010 HCS fiber optic links can be used with the system. Stations can be up to 45 m or 300 m apart. Power can be transmitted at 24 V DC with a range of -15% to +20%. The base current is 70 mA, and each of the four links needs 200 mA of K-bus current. Use in environments ranging from 0°C to +55°C. The coupler can also be stored at temperatures ranging from -25°C to +85°C. The Bk coupler has 64 bus connections and up to 256 digital inputs and outputs. This enables the connection of intricate control systems in a manner that can be expanded as necessary.

The BK2010 serial fieldbus coupler can connect to 64 bus terminals and has an IP20 grade for safety. In order to configure the product, users require either KS2000 software or a coupler that is capable of automatic mapping. The coupler is suitable for industrial automation networks that require a durable fiber optic interface and modular I/O expansion. Fast data flow, high-density digital I/O, and installation that can be changed all help make system design efficient and scalable.

Frequently Asked Questions about BK2010:

Q: Does BK2010 provide electrical isolation for safety?

A: The fieldbus coupler provides 500 V electrical isolation between power contacts and supply voltage. This ensures protection for both system electronics and connected devices.

Q: Why is the BK2010 data transfer rate set at 2.5 Mbaud?

A: A 2.5 Mbps data transfer rate in the fieldbus coupler allows fast and reliable communication. It minimizes latency for real-time industrial automation control.

Q: How does BK2010 handle power supply requirements?

A: The fieldbus coupler operates on 24 V DC with a tolerance of -15% to +20%. The coupler draws 70 mA plus K-bus current per four terminals, up to 200 mA.

Q: Do BK2010 fibre optic connectors increase station distance?

A: The fieldbus coupler uses BK2010 plastic and Z1010 HCS fibre optic connectors. This allows maximum distances of 45 m and 300 m between stations, respectively.

Q: Why does BK2010 have a protection class of IP20?

A: The fieldbus coupler features an IP20 protection class to prevent solid object ingress. It is suitable for installations where liquid protection is not required.
