## Description

Optocoupler Isolation Module,DC 12V 24V 8-Channe Optocoupler Isolation Board PNP NPN Low High Level Output Signal Converter: desertcart.com: Industrial & Scientific

Review: Nice for car arduino projects - Worked really well for isolating my arduino mega from 12v so I can detect switches and wires being live or not inside my car I used this so I could program my own dash lights to turn on and have different modes depending on if headlights were on or door was opened etc

## Features

- It can detect 8-Channel DC input power sources and output DC voltage according to the detection results.
- The output results can be applied to PLC system and other control equipment.
- It can detect whether there is input power. The output status will change when the input power is detected.
- Support DC 12V~24V Input.
- DC 1.8V-24V load voltage.
