Frequently Asked Questions (FAQ)

• Can I power this generator with 12V DC?
  It is recommended to use at least 15V DC to reliably generate a stable 0-10V output. Powering it with 12V may clip the top end of the 10V range.
• Does the LCD show the set value or the actual measured output?
  The LCD shows the programmed set value based on the encoder position.
• Can I switch the display to show percentage instead of voltage?
  Yes, you can program the display to show 0-100% (ideal for VFD speed referencing) or the actual 0-10.0V value.
• Will this remember my voltage setting if the power is turned off?
  Yes, the VSG01 has an internal memory feature that saves the last active state when powered down.
• Is the analog output galvanically isolated from the power supply?
  No, the input ground and output analog ground are common (shared).
• Can this output a negative voltage (e.g., -10V to +10V)?
  No, this unit only outputs positive DC voltage from 0V up to 10V.
• What is the maximum current the output pin can source?
  The output is designed for signaling, not power. It can safely source up to 20mA.
• Can this generate a 4-20mA current signal?
  No, the VSG01 is strictly a voltage signal generator. We stock the CSG01/CSG04 for 4-20mA current loop generation.
• How accurate is the voltage output?
  It is highly precise for standard process control, typically within ±0.1V accuracy.
• Can I use this to directly drive a small DC motor?
  No, it does not have the current capacity to drive motors. It must be connected to a motor controller or driver.
• What are the exact panel cutout dimensions?
  You need a rectangular cutout of exactly 77mm x 40mm to snap this unit in securely.
• Does the encoder knob click continuously or have hard stops?
  It is a continuous rotary encoder with soft detents (clicks) for precise step-by-step adjustment.
• Can I lock the knob to prevent accidental changes?
  Yes, pressing and holding the encoder knob typically locks the current value on these models.
• Is this compatible with an Arduino analog input?
  Yes, but you MUST set the generator's max output to 5V (or 3.3V) to avoid instantly destroying your Arduino's ADC pin.
• What wire gauge should I use for the screw terminals?
  Standard 22AWG to 18AWG stranded wire with crimped ferrules is highly recommended.
• How do I change the maximum output limit from 10V to 5V?
  This is adjusted by pressing the encoder knob to enter the setup menu, where you can cap the maximum voltage parameter.
