Sdvc31-S Variable Frequency Digital Controller for Vibratory Feeder

Sdvc31-S Variable Frequency Digital Controller for Vibratory Feeder. Variable Frequency Control: Manually adjust output frequency to match resonant frequency for smooth, quiet, and energy-saving feeding. Automatic Voltage Regulation: Internal digital circuit eliminates feed speed variation caused by mains voltage fluctuations. Time Adjustable Soft Start: Digitally preset soft start time gently increases voltage from 0 to avoid sudden shaking. Multiple Sensor Control: Supports NPN/PNP sensors, PLC remote control, and intelligent photoelectric sensor ON/OFF control. Remote Speed Adjustment: Adjust output voltage remotely via external potentiometer, PLC, or 1-5V DC signal. Comprehensive Protection: Features digital overheat, overcurrent, and restorable short-circuit protection with auto-recovery. Keypad Lock Function: Lock all buttons by holding ON/OFF for 2 seconds to prevent accidental misoperation. DC Control Output: Outputs low voltage DC power to drive solenoids or other external devices.
