2-Channel Optocoupler 12V Relay Module (10A/250V AC; 10A/30V DC)

This is a 2-channel optically isolated relay moduleis  used to switch high voltage circuits on and off, such as appliances.

The optical isolation means that your own circuit or device will be protected from any of the high voltage or high current surges.

1.Onboard EL817 optocoupler with optical isolation anti-jamming capability
2.Onboard 12V 10A/250VAC, 10A/30VDC relays, relay and long life can continuously pull 100,000 times
3.The module can be directly and microcontroller the I / O link output signal indicates
4.The module has a diode freewheeling protection with short response time.
5.PCB size: 44.4 (mm) x32.4 (mm)
