In the actual work encountered in the need for isolation control, and voltage conversion, will use this module.

Can realize 3.3V or 5V control 3.6--24V voltage level interface, realize the control side conducts, the controlled side also conducts.

Optical isolation anti-interference capability. The back can drive high-power transistors, MOS tubes and other occasions that require high voltage drive, but also can directly drive the small power 24V relay work.

If it is a pulse signal, please note that the limit of 817 is below 4KHZ, please do not use this module for control signals larger than 4KHZ, it will not work properly.

Module parameters:

1、Signal voltage at drive end: 3.6-24V

2, the output voltage range: 3.6-30V (output current depending on the specific circumstances, but do not 10MA, the total power must be Voltage and current is inversely proportional to)

3, through the jumper cap can realize the output is high potential output or pull down the output.

4, the board above the 4-way 817 are independent, you can realize different voltages at the same time control and so on.

5: board size: length: 48mm; width: 38mm; long side hole spacing: 42mm; wide side hole spacing: 32mm
