RDL ULTRASTYLE Design

The RLC‑10R is the ideal choice for 0 to 10 Vdc or pulsed control from a remote location. Circuitry is based on optical encoder technology to produce long‑term, trouble‑free operation. Control is incremented up or down when the large front‑panel knob is rotated. Acceleration is provided so the rate of change is faster when the knob is rotated more rapidly, yielding a responsive feel. The LED ring display encircling the control knob operates as a virtual pointer. The input to this display is a 0 to 10 Vdc signal, either internal or external.

A 0 to 10 Vdc output provides single point control for RDL VCA products and other industry 0 to 10 Vdc controlled equipment. If multiple control points are desired, individual up or down pulse outputs may be connected to RDL RU‑VCA products and various industry products. A rear‑panel jumper sets the pulse outputs to either produce +15 Vdc pulses (RDL RU‑VCA) or momentary open‑collector pulses.

In the event of power loss, internal non‑volatile memory stores the last level value. When power returns, the 0 to 10 V output will return to the operating level present when power was lost.
