ITEM NAME:Robotdyn Thyristor Ac Switch (Relay), 3.3V/5V Logic, Ac 220V/5A (Peak 10A) A9C2 Robotdyn Thyristor Ac Switch (Relay), 3.3V/5V Logic, Ac 220V/5A (Peak 10A) A9C2 If you need to control the power of Ca (lights, household equipment), a thyristor is what you need. This is a very common thyristor module with very low ignition resistance and a control voltage, compatible with any 3.3 V or 5 V Micro-controller or mechanical switch. This allows you to control high power devices with very low power control mechanism. This board has an opto insulator to protect your Micro-controller from high AC currents. colour:Color as shown Material:Plastic + metal size:4*11*3CM Package Contents: 1*Thyristor AC Switch.1 Thyristor AC Switch. colour:Color as shown.
