The EL6851 EtherCAT Terminal is a DMX master terminal and enables connection of up to 32 devices without repeater. The DMX master terminal can send up to 512 bytes of data (this can be set via the terminal). At 250 kbit/s a maximum data rate of 44 kHz is therefore possible. The RS485 interface in the EL6851 is electrically isolated and guarantees high interference immunity.
The Bus Terminal Controllers are Bus Couplers with integrated PLC functionality. The “Compact” BC5250 Bus Terminal Controller for DeviceNet extends the Beckhoff small controller series by a cost-optimized version in a compact housing. The DeviceNet Controller offers automatic baud rate detection up to 500 kbaud and two address selection switches for address assignment.
The BK1150 EtherCAT Coupler is the link between the EtherCAT protocol at fieldbus level and the Bus Terminals. The coupler converts the passing telegrams from Ethernet 100BASE-TX to the internal, fieldbus-independent terminal bus.
The BK5200 Bus Coupler connects the DeviceNet bus system to the electronic terminal blocks, which can be extended in modular fashion. One unit consists of one Bus Coupler, any number of up to 64 terminals and one end terminal.
The Compact Bus Coupler BK5250 for DeviceNet extends the Beckhoff Bus Terminal system by a cost-optimized version in a compact housing. Up to 64 Bus Terminals are supported; with the terminal bus extension, up to 255 Bus Terminals can be connected.
The Compact Bus Coupler BK7150 connects the CC-Link system to the electronic terminal blocks, which can be extended in modular fashion. One unit consists of the Bus Coupler, any number of up to 64 terminals and one end terminal. The K-bus extension technology allows the connection of up to 255 spatially distributed Bus Terminals to one Bus Coupler.
The BK9053 Bus Coupler connects PROFINET with the modular, extendable electronic terminal blocks. One unit consists of one Bus Coupler, any number from 1 to 64 terminals (255 with K-bus extension) and one end terminal.
The digital KL2784 Bus Terminal provides four switches that can be used like a relay contact for AC/DC voltages. The electronic switch is realized through high-performance MOSFET transistors with low switch-on resistance.
The switch itself is not short-circuit proof, but due to its high pulse current capability it can cope with current until an external fuse triggers a switch-off.
