About this item
  • This module is used when it is necessary to isolate the control in actual work and voltage conversion.
  • It can realize 3.3V or 5V to control the interface of 3.6--24V voltage level. After the control terminal is turned on, the controlled terminal will also be turned on.
  • Photoelectric isolation has strong anti-interference ability. The latter can drive high-power triodes, MOS tubes and other applications that require high-voltage driving, and can also directly drive low-power 24V relays.
  • If it is a pulse signal, please note that the limit of 817 is below 4KHZ. If the control signal is greater than 4KHZ, please do not use this module, it will not work properly.
Product description

Module parameters: 1. The drive terminal signal voltage: 3.6-24V 2. The output voltage range: 3.6-30V (output current depends on the specific situation, but the maximum is not 10MA, the total power is certain, the voltage and current are inversely proportional) 3. Through the jumper cap can achieve whether the output is high potential output or low output. 4. The board 2 above 817 are independent, can achieve simultaneous control of different voltages, etc. Package include: 5 x module

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
