I2C 듀얼 2채널 SSR 릴레이 -25A/250VAC
(SparkFun Qwiic Dual Solid State Relay)
개요
- 본 제품은 I2C 듀얼 2채널 SSR 릴레이입니다.
- 두개의 AC 부하를 마이크로컨트롤러에서 제어할 수 있게 하여 주는 제품입니다.
- 보드에는 Zero Cross Trigger 식 두개의 25A/250VAC 솔리드 스테이트 릴레이를 장착하고 있어, 초당 120회까지 60Hz AC 신호상의 두개의 부하를 On/Off 토글 시킬 수 있습니다.
- 보드에는 ATTiny84 MCU가 장착되어 있어 I2C 명령을 받아서 두개의 릴레이를 동작시킬 수 있게 디자인되었습니다.
- ATTiny84의 I2C 주소는 소프트웨어 설정이 가능합니다.

Messing with such high voltage is dangerous! We've included many safety precautions onto the PCB including ground isolation between the relay and other circuitry and a milled out area isolating each side of AC. However, with all the safety precautions included with the SparkFun Qwiic Dual Solid State Relay, this is still a power accessory for users who are experienced around, and knowledgeable about high AC voltage. If you're not comfortable with handling AC voltage in this way, you may want to check out the IoT Power Relay instead.
Note: The relays are rated for a max of 25A with forced air cooling. If you do not have forced air cooling, 10A max through the relays is recommended.
