817 Optocoupler 2/4/8 Circuit Voltage Isolation Board
Product Introduction:
When encountering the need for isolation control and voltage conversion in practical work, this module will be used.
The interface can control the voltage levels of 3.6-24V at 3.3V or 5V, and after the control terminal is turned on, the controlled terminal will also be turned on.
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.
Module parameters:
1. Drive end signal voltage: 3.6-24V
2. Output voltage range: 3.6-30V (output current depends on the specific situation, but not 10MA, total power is inversely proportional to voltage and current)
3. The jumper cap can be used to determine whether the output terminal is high potential output or low output.
4. The four 817 circuits on the board are all independent, which can achieve simultaneous control of different voltages, etc
5: Board size: length: 48mm; Width: 38mm; Long edge hole spacing: 42mm; Wide edge hole spacing: 32mm
