When encountering the need for isolation control and voltage conversion in practical work, this module is used.
It can achieve 3.3V or 5V control for interfaces with voltage levels of 3.6-24V. After the control end is turned on, the controlled end will also be turned on.
The photoelectric isolation has strong anti-interference ability. In the future, it can drive high-power transistors, MOSFETs, and other applications that require high voltage driving, and can also directly drive low-power 24V relays to work.
If it is a pulse signal, please note that the limit of 817 is below 4KHZ. Control signals greater than 4KHZ should not use this module as it will not work properly.
Module parameters:
1. Driver 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 constant, voltage and current are inversely proportional)
3. The jumper cap can be used to determine whether the output terminal is a high voltage output or a low voltage output.
4. The 4 channels 817 on the board are all independent and can achieve simultaneous control of different voltages
5: Board size: Length: 48mm; Width: 38mm; Long side hole spacing: 42mm; Wide side hole spacing: 32mm
