Analog, Pulse, or Floating Point to Resistive Output

The SC-DRN3.1 is an interface that allows microprocessor control of a variable resistance. The SC-DRN3.1’s isolated resistor network can be controlled by several different DDC signal types. It directly replaces a variable resistance controller and simulates the action of a slide wire or rotary potentiometer. All connections of the simu¬lated potentiometer, the wiper and both ends of the resistance range, are available on the SC-DRN3.1 terminal strip. The SC-DRN3.1 accepts an analog, pulse of floating point input signal (including TRIAC) and converts it into a proportional resistive output.
