2pcs PC817 8 Channel Optocoupler Isolation Board 817 Voltage Isolation Module Voltage Converter Module 3.6-30V Photoelectric Isolated Module(2/4/8 Channel Optional)

Description: It 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.
Features: 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
Note: The input port is shared with GND; The output ports are independent each other; It is optocoupler output. V and G will be connected after input valid signa in input port. Pack of 2 pieces, it means you will get them two SAME units in one type, not two mixed types.
Package included: 2 x PC817 Optocoupler Isolation Board(2/4/8 Channel Optional, two SAME units in one type)
