    Analog terminal with two input and two output channels, -10 V to 10 V The KL4494 Bus Terminal combines two analog inputs and two analog outputs in one housing and can process signals in the range -10 V to +10 V. The voltage is digitized to a resolution of 12 bits, and is transmitted, electrically isolated, to the higher-level automation device or to the process level.

    Basic function principles Analog input channels The analog input channels of the KL4494 process signals in the range from -10 V to +10 V with 12-bit resolution (4095 steps). The inputs are single-ended inputs with a common ground potential. Format of the input values In the delivery state the process data are shown in two's complement form ( -1 corresponds to 0xFFFF).
  • Page 9 The equations of the straight line are activated via register R32. Analog output channels The analog output channels of the KL4494 generate signals in the range from -10 V to +10 V with a resolution of 12 bits (4095 steps). The outputs are single-ended outputs with a common ground potential.
