he KL4434 analog output terminal generates signals in the range between -10 to +10 V. The voltage is supplied to the process level with a resolution of 12 bits and is electrically isolated. In the KL4434, the four outputs are 2-wire versions.
The input and output channels of the Bus Terminal have a common ground potential. The run LEDs give an indication of the data exchange with the Bus Coupler.
