Quad Trigger to Solenoid Motor Driver


Solenoid can drive 4 solenoid motors with voltage directly from the power supply. Motor driving circuitry and CV input circuitry are optically isolated without any ground connection. Requires external power supply for driving motors. Output pulse width a knob optimizes the trigger signals to be sufficient to deliver an adequate signal for the solenoids. With shorter pulses, solenoids don`t move in their full range or move with less power. This can also be used for adjusting the dynamics.


  • four-channel solenoid motor driver
  • CV circuitry and motor circuitry are optically isolated
  • external power supply for motors required
  • motors are driven directly from the external power supply
  • trigger input per channel
  • Output pulse width knob applies to all channels
  • handmade locally by Bastl Instruments in Brno, Czech Republic
  • individual CV control for the velocity of each channel with Solenoid Exp
