There is a KL9050-Beckhoff bus extension coupler-terminal. The KL9050 coupler terminal supersedes the Bus Coupler on a Bus Terminal block. The KL9050 is the obverse to the KL9020. The S(F)TP cable (shielded convoluted pair) is plugged into the upper socket, providing the logical connection to the Bus Coupler. The extension is plenarily transparent for the Bus Coupler. All Bus Terminal system functions remain unchanged. An incipient KL9050 can be connected to the first coupler terminal.
The whole system can thereby be elongated by 31 stations. The supply voltage for the field level for KL9050 a 400 mA K-bus power supply unit supplies the integrated Bus Terminals. The internal electronics and the field level can be supplied together from a single voltage source.

Three diagnostic LEDs give information about the supply voltage for each Bus Terminal block internal and field level. The KL9050 can be utilized as the last coupler terminal in the system or as a bridge between two Bus Terminal blocks. Canto replaces these two functions with a selector switch. The switch must be opportunely situated for the system to operate.
