Product Description:

The BK9055 Bus Coupler of the Beckhoff company is an EtherNet/IP protocol-based coupler. It supports configuration either via the KS2000 software or the TwinCAT controller used in industrial automation. The coupler establishes its connection via a single RJ45 port to ensure safe data transmission. The coupler supports 64 Bus Terminals and can be extended to 255 terminals with the use of a K-Bus extension.

The BK9055 bus coupler supports a maximum of 492 bytes of input data and 492 bytes of output data. Bus Coupler manages 3,936 digital peripheral signals and 122 analog peripheral signals. The IP address space dictates the number of I/O modules. The data transfer rate is selectable as 10 Mbit/s or 100 Mbit/s. The maximum distance between modules permitted is 100 meters. The contact voltage of power is 24 VDC, with a 10 A maximum power contact load. The BK9055 bus coupler employs twisted pair copper cable with 4 × 2 shielding for signal integrity. It accommodates category 5 cable for 100 Mbit/s or category 3 cable for 10 Mbit/s. Power supply is 24 VDC with a tolerance of -15% to +20%. Current consumption is 70 mA plus the total current for K-Bus, with a maximum of 4500 mA. Dielectric strength is ensured at 500 V over system connections.

The BK9055 bus coupler has a weight of around 100 g for light mounting. It is suitable for DIN rail mounting as per EN 60715 standards. It can withstand up to 95 percent humidity. The protection class is IP20 rated for indoor applications. EMC resistance against burst and ESD is as per EN 61000-6-2 and EN 61000-6-4 guidelines. The product is also resistant against vibration and shocks.
