The KL6021 serial interface allows devices with an RS422 or RS485 interface to be connected. The device connected to the terminal communicates with the automation device via the Bus Coupler.
The KL6051 serial interface terminal makes it possible to exchange data between different fieldbus systems. Full duplex data exchange is possible, independently of the higher-level fieldbus. Under the terminal’s default setting, 32 inputs and 32 outputs are transferred between the fieldbus systems.
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.
The KL9020 is attached to the end of the Bus Terminal block in the same way as the standard terminal KL9010 and terminates the terminal block. The KL9020 enables the connection of an Ethernet cable with a RJ45 plug.
The KL9050 coupler terminal replaces the Bus Coupler on a Bus Terminal block. The KL9050 is the counterpart to the KL9020. The S(F)TP cable (shielded twisted pair) is plugged into the upper socket, providing the logical connection to the Bus Coupler.
The KL9080 is used to identify potential groups (e.g. 230 V AC/24 V DC). It is inserted between two potential groups, and indicates the separation through an orange cover.
