The EL9550 system terminal contains an overvoltage filter for the 24 V field and system supply. The filter protects the EtherCAT Terminal from line-bound surge voltages that can occur due to high-energy, dynamic disturbances such as switching overvoltages at inductive consumers or indirect lightning strikes at the supply lines.
The EL9080 separation terminal is used for the separation and marking of different potential groups (e.g., 230 V AC/24 V DC). It is inserted between two potential groups, and indicates the separation through an orange colored cover. The E-bus is passed through in the usual way to the adjacent terminal.
The EL9186 potential distribution terminal provides 8 terminal points with the 24 V potential at the front on the terminal contacts. The 24 V power contact is connected to the front-side terminal contacts and is passed through to the adjacent terminal. The 0 V power contact is not connected to the front-side terminal contacts and is passed through to the adjacent terminal. With the EL9186, the use of additional terminal blocks on the terminal strip can be reduced.
The EL9187 potential distribution terminal provides 8 terminal points with the 0 V potential at the front on the terminal contacts. The 0 V power contact is connected to the front-side terminal contacts and is passed through to the adjacent terminal.
The EL9188 potential distribution terminal provides 16 terminal points with the 24 V potential at the front on the terminal contacts. The 24 V power contact is connected to the front-side terminal contacts and is passed through to the adjacent terminal.
The EL9189 potential distribution terminal provides 16 terminal points with the 0 V potential at the front on the terminal contacts. The 0 V power contact is connected to the front-side terminal contacts and is passed through to the adjacent terminal.
The BC3100 Bus Terminal Controller is a Bus Coupler with integrated PLC functionality and has a fieldbus interface for PROFIBUS. It is an intelligent slave and can be used as distributed intelligence in the PROFIBUS system. In the BC3100, one unit consists of the controller, between 1 and 64 terminals, and a bus end terminal.
The BC3150 Compact Bus Terminal Controller in a compact housing is a Bus Coupler with integrated PLC functionality and has a fieldbus interface for PROFIBUS.
The Bus Terminal Controllers are Bus Couplers with integrated PLC functionality. The Compact BC5150 Bus Terminal Controller for CANopen extends the Beckhoff small controller series by a cost-optimized version in a compact housing. The CANopen controller offers automatic baud rate detection up to 1 Mbaud and two address selection switches for address assignment.
The Bus Terminal Controller BC7300 is a Bus Coupler with integrated PLC functionality and has a fieldbus interface for Modbus. The BC7300 is an intelligent slave and can be used as a non-central intelligence in the Modbus system.
The BC8050 Compact Bus Terminal Controller with serial RS485 interface extends the Beckhoff small controller series by a cost-optimized version in a compact housing. An open serial protocol – like in the BK8x00 Bus Couplers – and the Modbus RTU/ASCII protocol are implemented. The address and the protocol are selected via the two rotary selection switches.
