Relay Module

Product Details:

ADIY PC817 2 Channel Optocoupler Isolation Board. Onboard with 4-Channel PC817 are independent, so they can achieve different voltage control at the same time. Using 4-way PC817 optocoupler, to achieve the control signal and the control signal isolation, you can directly use the microcontroller or other devices IO port to achieve the voltage isolation control, you can achieve a small voltage control, the control side can be an external transistor MOS tube or different voltage levels of the device interface.

Pin Description:

• Input pins:

1. IN   : Input 5V to 30V
2. GND: Ground

• Output Pins:

1. OUT: Phototransistor collector pin
2. GND: Phototransistor emitter pin

Applications:

• I/O isolation for MCUs (Micro Controller Units)
• Noise Suppression in Switching Circuits
• Signal Transmission Between Circuits of Different Potentials and Impedances

Additional Information:

• Item Code: adiy-pc817

Product Details:

This module can be used for light detection, brightness detection, with power indicator light (red) and relay indicator (blue), and with four M3 screw mounting holes, which is convenient to install, the board can adjust the sensitivity of the potentiometer, with relay, to do a variety of brightness detection and control switch, can be used in the street for example at night, during the day to open automatically, automatically extinguished, and other automation equipment.

Features:

1. With anti-reverse function, reverse the power supply will not damage the module
2. The light threshold can be adjusted by Potentiometer to set the relay start
3. Module output terminal has three ports
4. RED LED ON: Indicate the Power ON
5. BLUE LED ON: Relay is working
6. Relay Pinouts
   • Normally open ( NO )
   • Common terminal ( COM )
   • Normally closed ( NC )
