Note: This is a relay device and the circuits are exposed. DO NOT touch the components onboard! We recommend you to add insulate enclosure when using. The device will get hot when working, higher the output power, hotter it is. The device will cut off output signal to protect the TRIAC when the temperate reaches 125°C. We recommend you to add cooling devices to let the TRIAC HAT work normally under 80°C.
