bottom side
  • POT4a is a green PCB with white silk screen on two sides.
  • Dimensions 1.75" x 0.85"
  • Two mounting holes (diameter = 0.125"), top side clearance > 0.25"
  • The color of DL1,DL2 indicates the input configuration of the board


Led Indicators

  • (DL1, DL2) : A pair of single LEDs indicate the present of power. These LEDs are aligned with the power input to the boards.
  • DK1 : The intensity of this dual RED/GREEN LED indicates the voltage of the "position signal".
