KL9020 | Terminal bus extension, end terminal

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 K-bus signals are converted to RS485. Power to the KL9020 electronics is supplied via the K-bus. The KL9020 forms a properly working unit together with at least one KL9050. Apart from a supply voltage of 24 V and the insertion of the Ethernet cable, there is no further parameterization or configuration work necessary. The Bus Coupler carries out all diagnosis and commissioning tasks.
