Optocoupler Galvanic Isolation Module - PC817

This module is helpful in connecting digital systems (e.g. 5V microcontrollers) to a high voltage system. The board electrically isolates the driver from the high-voltage circuit by means of an optical isolation IC. The IC has built-in two LEDs and two photodiodes.
This allows the low voltage side to control the high voltage side.
The module has LEDs that indicate the operation of each channel. There are also two jumpers, one per channel, thanks to which you can disconnect the executive system, e.g. during testing instead of unscrewing the wires from the ARK connector
A frequently used board to prevent electromagnetic interference when controlling e.g. motors with a higher voltage than the microcontroller that controls them. This board isolates systems by creating a barrier between devices.

Isolator module, signal separator based on optocouplers.

The module allows to isolate the microcontroller from executive circuits characterized by a high level of interference.

It is suitable for controlling relays, contactors and other actuators that generate overvoltages.

The module is based on the PC817 chip. The module does not invert the signal logic.

There are jumpers on the board that pull up the output signal to ground.
