About this product
A two-channel 12V DC relay module with optocoupler isolation, indicator LEDs for each channel and back-EMF protection. Each relay switches up to 10A at 250VAC or 30VDC through C, NC and NO screw terminals, so it can drive lamps, fans, solenoids and motors from a 3.3V or 5V microcontroller.

Frequently asked questions
What is the price of 2-Channel 12V Relay Module with Optocoupler HW-383 in Egypt?
2-Channel 12V Relay Module with Optocoupler HW-383 currently costs 55 EGP in Egypt.
Where can I buy 2-Channel 12V Relay Module with Optocoupler HW-383 in Egypt?
2-Channel 12V Relay Module with Optocoupler HW-383 is available from Microohm. Compare the offers above to find the best price.
Can I control it from a 3.3V board such as ESP32?
Yes. The listed trigger input range is 3.3V to 5V, so the input signal can come from a 3.3V microcontroller pin such as an ESP32 GPIO.
Can it switch mains AC loads?
The contacts are rated 10A at 250VAC, so AC loads are supported. Mains wiring must be insulated and enclosed properly, and should be done by a qualified person. Keep the high-voltage side away from the low-voltage control side.
