Output terminal voltage range: 3.6-30V (output current depends on the specific situation but the maximum does not exceed 10MA, the total power is constant, the voltage and current are inversely proportional) Whether the output is a high potential output or a low potential can be realized by a jumper cap. The 4 channels 817 are separated., can achieve simultaneous control of different voltages, etc. Board size: 48mm x 38mm (length and width); long side hole distance: 42mm; wide side hole distance: 32mm Package Inluded: 1pcs NOYITO PC817 4-Channel Optocoupler Isolation Board

Review: A great solution for dissimilar voltages - I needed to interface a 12V alarm system into a component of my own design (5V). I wanted isolation and voltage conversion. This board worked fine. Some of the other reviews mentioned that grounds are connected together. This is true, and caused issues with interaction in my design. Wished that I could separate the Grounds. To solve this issue, I ordered the two channel version of the same optocoupler. In fact, I ordered a selection of the product with a selection of channels for future projects. I did find that if you use a number of these boards for I/O it can become quite a mess of wires. Nevertheless, they do a good job and I have found that they work through a wide voltage range. Great product. Recommended.
Review: Fantastic optocoupler for digital logic voltage conversion - If you have a project which requires voltage level conversion or voltage isolation to reduce noise, then this board is what you need. For example, I completed a project with 12V logic inputs and outputs over a long noisy wiring run. Those 12V lines are translated though this octocoupler to switch 3V3 lines on a very sensitive microcontroler. Note: pull-up or pull-down resistors are required since this octocoupler is floating. However, the end result is a 100% reliable voltage level conversion, even when deployed in some very harsh conditions. The only limitation of this octocoupler is that the switching is too slow to translate a serial type bus, I2C, or SPI. It is really only appropriate for digital logic. Also, each channel on the octocouplter can operate at independent voltage levels, meaning that all 4 channels do not have to share the same reference voltage, such as with a transistor based logic level converter. I am extremely happy with the quality, design, and performance of this module and will make it a go to going forward.

## Features

- This module is used when it comes to the need for isolation control and voltage conversion.
- Drive terminal signal voltage: 3.6-24V. Output terminal voltage range: 3.6-30V (output current depends on the specific situation but the maximum does not exceed 10MA, the total power is constant, the voltage and current are inversely proportional)
- It can realize 3.3V or 5V to control the interface of 3.6-30V voltage . After the control terminal is turned on, the controlled terminal will also be turned on.
- Photoelectric isolation has strong anti-interference ability. It 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 4KHZ or less. If the control signal is greater than 4KHZ, please do not use this module, it will not work properly.

### ⭐⭐⭐⭐ Not super clear info.
*by E***R on May 22, 2023*

Works fine but connectors are very finicky..the instructions could be clearer on configuration..also there is a 3 k resistor in series with the output v terminal so the actual isolated output v is going to depend on the load resistance. I used this as an emitter follower by removing the ground jumper... still not exactly clear on possible configuration and pull up pull down resistors. But works fine...leds built in is nice...
