RDL RLC-10RS overview

  • 1Description

The RLC-10RS Rotary Level Control from RDL is suitable for 0 to 10 VDC or pulsed control operations from a remote location. The encoder's circuitry is based on optical encoder technology for long-term, trouble-free operation.

Two output modes are simultaneously available. The 0 to 10 VDC output operates continuously and is used for single point control. This output is used to control RDL VCA products, and may be connected to a wide range of other industry 0 to 10 VDC controlled equipment. If multiple control points are desired, the pulse outputs may be connected to RDL RU-VCA products and various other industry products.

Up and down pulses from the optical encoder are also provided on the rear barrier block. A rear-panel jumper sets the pulse outputs to either produce +15 VDC pulses or momentary open collector pulses. Control is incremented up or down when the large front-panel knob is rotated and 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. A strap on the module rear barrier block determines if the display operates from the internally generated control voltage or from an external control voltage. Typically, if the 0 to 10 VDC control voltage from the RLC-10R is being used to control a VCA, the internal voltage is also used for the display. If the RLC-10R pulse outputs are used with RDL RU-VCA modules, the 0 to 10 VDC EQRAMP from the VCA module is fed back to the RLC-10R. Therefore, multiple RLC-10R modules may be connected together with all modules providing the same level indication.

In the event of power loss, internal non-volatile memory stores the last level value. When power returns, the 0 to 10V output will return to the operating level present when power was lost. The encoder can be used individually, or combined with other RDL products as part of a complete audio/video system.
