Beckhoff KL9050 internal bus extension coupler terminal
Brand:
Beckhoff Automation GmbH
Model:
KL9050
EAN:
Internal ArtNr:
1234589006
Description
The KL9050 coupler terminal replaces the bus coupler on a bus terminal block and forms the counterpart to the KL9020. The STP cable (Shielded Twisted Pair) is plugged into the top socket and creates the logical connection to the bus coupler. The extension is completely transparent for the bus coupler. All functions of the bus terminal system remain unchanged. The second RJ45 socket enables further system extension. Additional coupler terminals can be connected to the first coupler terminal, so that the entire system can be expanded in 31 stages. The supply voltage for the field level and the internal electronics can be fed in separately. Both levels are therefore galvanically separated from each other. In the KL9050, a 400 mA power supply supplies the K-bus for the subsequent bus terminals. The internal electronics and the field level are powered together from one voltage source. Three diagnostic LEDs provide information about the supply voltage for the respective bus terminal block. The KL9050 can be used as the last coupler terminal in the system or as a bridge between two bus terminal blocks.
