The BK1120 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 KL1194 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal contains four channels that indicate its signal state by means of light emitting diodes.
The input and output channels of the Bus Terminal have a common ground potential. The run LEDs give an indication of the data exchange with the Bus Coupler.
The KL9010 bus end terminal is necessary for data exchange between the Bus Coupler and the Bus Terminals. Each assembly must be terminated at the right hand end with a KL9010 bus end terminal. The bus end terminal does not have any other function or connection facility.
This module is a multifunction digital signal processor module. It can be used extremely flexibly for a wide variety of tasks involving digital signal processing or digital signal generation.
