3Pcs RobotDyn® Thyristor AC Switch Relay Module 3.3V/5V Logic AC 220V/5A Peak 10A

Feature: If you need to control the AC power (lights, home equipment's) a thyristor is what you need. This is a very common thyristor module with very low on-resistance and a control voltage, that is compatible with any 3.3V or 5V micro-controller or mechanical switch. This allows you to control high-power devices with very low-power control mechanisms. This board has an optoisolator to protect your micro-controller from high AC currents. We also left more space, if you need to install the heat sink for thyristor. Characteristics: Signal: DC3.3V/5V 10mA Commutation: VAC 220V/5A (peak 10A) Size: 22 x 46 mm Technical Instruction: GND to GND Signal (VCC) to Digital I/O, or 3.3V~5V Package includes: 3 x Thyristor AC Switch Relay Module
