The BK7500 Bus Coupler connects the SERCOS bus system with the electronic terminal blocks, which can be extended in modular fashion. One unit consists of one Bus Coupler, any number from 1 to 64 terminals and one end terminal. The Bus Coupler recognizes the connected terminals and automatically generates the affiliations of the inputs/outputs to the bytes of the process image.
The analog input terminal KL3404 processes signals in the range between -10 and +10 V. The voltage is digitized to a resolution of 12 bits and is transmitted, electrically isolated, to the higher-level automation device.
The KL4404 analog output terminal generates signals in the range between 0 to 10 V. The voltage is supplied to the process level with a resolution of 12 bits and is electrically isolated.
