DRN-series Interface Device

The DRN-series comprises a list of interface device that allows microprocessor control of a variable resistance. The DRN-series 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 simulated potentiometer, the wiper, and both ends of the resistance range are available on the terminal strip. The DRN-series has two sub sections the DRN3.1s and DRN4.

The DRN3.1 must be ordered with a Resistance Network. The DRN3.1 accepts Analog, Pulse, or Floating Point input signals (including triac) and converts them into a proportional resistive output. The output resistance does not wrap around if the input signal exceeds the highest or lowest selected input value. The DRN4 input signal types are field selectable by an 8-position DIP switch. The floating point input accepts two digital signals, one for increase and the other for decrease. The floating point full scale rate of change is 55 seconds. The DRN4 is supplied in an enclosure that can be directly mounted to a 1/2 inch knockout on the motor actuator.
