Your cart is empty. PC817 Optocoupler Module can achieve an interface with a voltage level of 3.6-24V controlled by 3.3V or 5V. After the control terminal is connected, the controlled terminal will also be connected. Strong photoelectric isolation and anti-interference ability. Later, it can drive high-power transistors, MOS transistors, and other occasions that require high voltage driving, or directly drive low-power 24V relays to work. If it is a pulse signal, please note that the limit of 817 is below 4KHZ. For control signals greater than 4KHZ, please do not use this module as it will not work properly.
PC817 Parameters:
Driving Port Signal Voltage:3.6-24V
Output Port Voltage Port: 3.6-30V
The jumper cap can be used to determine whether the output terminal is high potential output or low output.
Each channel of PC817 Optocoupler Isolation Board is independent, can control different voltage at then same time.
Package include: 8pcs PC817 2 Channel Optocoupler Isolation Board
Note:
The input port is shared with GND;
The output ports are independent of each other;
It is optocoupler output.V and G will be connected after input valid signa in input port.

Got these for arduino power engineering projects. These have an accommodating voltage range and it's convenient how many you get, since you'll probably want to make more and more projects. You can drive 24v relays with this and switch even larger loads. Recommend.

This is a really good deal on 8 optocouplers. Plus they are dual channel so you actually get 16 of them.I am using these for alternate energy projects where I need to isolate one source from another. These are perfect for the job.At this price point I am going to save this seller.
