BK5150

What type of industrial component is this?

It is a compact CANopen Bus Coupler designed to connect modular Bus Terminals to a CANopen fieldbus network. The BK5150 acts as the communication interface between the network controller and the connected input/output terminals.

What supply voltage does the coupler require?

The coupler requires a nominal 24 V DC supply and accepts a tolerance of -15% to +20%.

Which fieldbus protocol does it use?

It uses CANopen and supports communication functions including process data objects, service data objects, heartbeat, node guarding and emergency messages.

How many Bus Terminals can be connected?

Up to 64 Bus Terminals can be connected directly. With suitable K-bus extension terminals, the system can be expanded to accommodate as many as 255 Bus Terminals.

What is the maximum process-data capacity?

The coupler supports up to 512 bytes of input data and 512 bytes of output data, allowing it to handle combinations of digital, analogue and specialist terminal signals.

How many digital and analogue signals can it handle?

The BK5150 can accommodate up to 256 digital input/output signals and up to 128 analogue input/output signals, subject to the selected terminal arrangement and process-data limits.

Which CANopen transmission rates are supported?

Supported rates range from 10 kbaud to 1 Mbaud. Available settings include 10, 20, 50, 100, 125, 250, 400, 500 and 800 kbaud, as well as 1 Mbaud.

How is the CANopen node address selected?

The node address is set using the rotary address selectors on the front of the coupler. The selected address must be unique within the CANopen network.

What type of fieldbus connector is fitted?

The fieldbus connection uses a five-pin open-style plug connector for CAN ground, CAN low, shielding and CAN high connections.

How is the unit mounted?

The unit clips onto a standard 35 mm mounting rail conforming to EN 60715. Compatible Bus Terminals are installed directly to its right-hand side.

What is the available K-bus current?

The integrated 5 V K-bus supply provides up to 1,000 mA for the electronics of the connected Bus Terminals.

What current can the power contacts carry?

The power contacts are rated for a maximum continuous load of 10 A, with a maximum power-contact voltage of 24 V DC.

Does it provide electrical isolation?

Yes. It provides 500 V electrical isolation between the fieldbus, supply voltage and power-contact sections.

What operating temperature range is permitted?

The permitted ambient temperature during operation is 0°C to +55°C. For storage, the permitted range is -25°C to +85°C, with relative humidity up to 95% without condensation.

What enclosure protection rating does it have?

The coupler has an IP20 protection rating. It is intended for installation inside a suitable control cabinet or enclosed industrial assembly.

What do the front status indicators show?

The front LEDs provide visual information about fieldbus communication, power conditions and K-bus status, helping operators identify network or terminal-level faults.

Can digital, analogue and specialist terminals be used together?

Yes. A terminal station can combine compatible digital, analogue and specialist Bus Terminals, provided the total terminal count, K-bus current and process-data capacity remain within the coupler's limits.

What CANopen process-data features are supported?

The coupler supports up to 16 receive PDOs and 16 transmit PDOs, along with variable mapping for organising input and output data within the CANopen process image.
