Sdvc21-S (5A) Variable Voltage Digital Controller for Vibratory Feeder. Automatic Voltage Regulation: Internal digital circuit reduces feed speed variation caused by mains voltage fluctuation. Time Adjustable Soft Start: Digitally preset soft start time avoids sudden shock by gently increasing output voltage. 4 Preset Feed Speeds: Four feed speeds can be preset, stored, and outputted via external short-circuit signals. Dual Switch Sensor Control: Supports 2 NPN switch sensors or PLCs for ON/OFF control of the controller. Photoelectric Sensor Control: Connect CUH Intelligent Photoelectric Sensor to turn on/off the controller. Remote Speed Control: Adjust output voltage remotely via external potentiometer, PLC, or 1-5V DC signal. Comprehensive Protection: Features overheat, overcurrent, overvoltage, and fuse-short circuit protection. DC Control Output: Outputs low-voltage DC power for ON/OFF control to drive solenoids or external devices.
