MY1065 Digital Pot

A useful little device to set machine speed without having to run a 10 volt reference from the controller. Can be reset when the machine stops so on restarting the speed is zero and the machine will not run away unexpectedly. Using a digital pot which has no end stops allows for a better resolution for fine tuning but still reaches it‘s maximum value quickly unlike a 10 turn potentiometer. A mechanical device is still more friendly than trying to watch a process and adjust a touch screen value at the same time

  • Endless encoder pot with 0 to 10v dc 1024 step analogue voltage output.
  • Speed monitored adjustment. Turn slow for fine adjustment, fast for rapid change of output
  • Reset input switches off the pot and resets the output to 0 volts.
  • Push on/push off push button to enable the device, also switches on a voltage free contact
  • A link on the PCB switches the relay contact from being normally open to normally closed. (only when powered up)
  • On board precision 10 volt reference
  • 20KOhm equivalent output resistance.
