Electronic Controller for NPN-PNP sensor.

SKU: PRX99 Categories: ,
General Details

The PRX99 electronic vibrator stop circuit can be used to stop round electromagnetic vibrators or electromagnetic vibratory hoppers through mechanical, inductive, capacitive or optical (photocells) sensors with NPN or PNP outputs. the circuit also features 2 timed delays 0-12 sec. which are adjustable, for stop and start of the vibrator.


Circuit PRX99 with external regulation by potentiometers-code PRX99/PEX.


The PRX99 electronic vibrator stop circuit can be used in various configurations, such as:

  1. for controlling overflow of a vibratory chute at the output of a round vibrator.
  2. for controlling the loading in a round vibrator from a hopper by means of mechanical level indicators.
  3. for energizing readout photocells instead of the mechanical device used as level sensor.
  4. delay for alarm absance pieces – red led.
  5. supply EV air blow (24Vcc) with delay (2 sec.)
  6. delay on vibrator (0-12 sec.) – delay off vibrator (0-12 sec.)
  7. pover supply 24Vca – 0.1A max.
