S-DTY220d40p SSR Relay 4-20mA 0-10V AC Solid State Relay Single-Phase Fully Isolated AC Voltage Regulator Module

S-DTY220d40p SSR Relay 4-20mA 0-10V AC Solid State Relay Single-Phase Fully Isolated AC Voltage Regulator Module. Fully Isolated Design: Input and output are opto-isolated for safe control of high voltage by weak signals. Multi-Function Regulation: Integrates phase shift, cycle wave, and PWM adjusting for precise power control. Wide Input Signal Options: Supports 0-5V, 0-10V, 4-20mA, and Potentiometer input signals. High Precision Control: Single-chip microcomputer design solves signal inaccuracy and unstable adjustment. Versatile Applications: Ideal for lighting, temperature control, AC motor soft start, and speed control. High Input Impedance: Can be directly connected to computers or D/A converters for infinite adjustment.
