Product Description

 The BK3520 EtherCAT Bus Coupler is a bus-coupler device created by Beckhoff. This device makes data transmission between different automation devices easy. It is a member of Beckhoff's BK EtherCAT Bus Coupler Series. Its automated identification of data transmission rates up to 12 Mbaud is one of its primary characteristics. Through throughput maximization, delay reduction, and network adaptation, this dynamic adjustment guarantees maximum communication efficiency. Complex automation activities need the BK3520's capabilities for many input/output (I/O) connections. With its ability to control up to 1,020 digital and 64 analog peripheral I/Os, it can integrate a variety of devices, from basic sensors to complex actuators.

The broad I/O capabilities enable thorough data control and collection, meeting a variety of automation needs. A maximum capacity of 24 V DC and 10 A power connections are also included in the BK3520. The coupler can power connected devices directly thanks to its integrated power handling capabilities, which also simplify system design and wiring complexity. The automation system is made more compact and efficient by this feature, which reduces the requirement for external power supply and related wiring. The performance and dependability of the BK3520 are also significantly influenced by its physical attributes.

Because it is lightweight—it weighs around 170 grams—it may be used in a variety of installation situations while putting the least amount of pressure on mounting structures. The coupler's operating temperature range of 0 to +55°C guarantees dependable functioning in a variety of industrial settings, including ones with temperature fluctuations. Because of its broad working range, the coupler is more adaptable and suitable for demanding applications. Wake Industrial gives customers confidence and peace of mind about the BK3520's quality and dependability with a one-year guarantee.
