Frequency controller up to 5A with a solid state appearance. Perfect to avoid mechanical tuning.

General Details

Microprocessor digital professional controller with visualized frequency (optional) up to 5 A – Delay 4 sec max ON/OFF vibrator with sensor NPN/PNP or relay contact – alarm absence pieces (8 sec.) – Air blow – Automatic Input from PLC 0/10V – 4/20mA – Status Relay.

General Characteristics

  • Voltage (110V) 230V, 50-60 Hz
  • Double Input ON/OFF • Soft/fast ramp
  • Manual Regulation Amplitude/Frequency (30/80Hz – 80/130Hz)
  • 3000/6000 V/m
  • Line input with schuko plug
  • Vibrator output with connector.


  • Personalized label
  • Connector for vibrator
  • Display Frequency Meter
  • Available Frequency Regulation by inside trimmer
  • Frequency regulation with knob blocked or with keys.


Digital regulation of linear and bowl feeder till 5 Amps. The RF4 PWM allows optimizing operation of the vibratory feeder by searching for its resonance frequency (max performance) thereby eliminating its lengthy and difficult mechanical calibration.
