Product Overview: Multi-Channel Isolator Board

This module provides a safe bridge between low-power microcontrollers and high-power industrial components. By converting electrical signals into light and back again, it ensures that there is no physical electrical connection between your MCU and the load, effectively acting as a “firewall” for your circuit.

Core Features

Total Electrical Isolation: Protects sensitive pins on your Arduino or ESP32 from “back-EMF” and high-voltage surges.
Dual-Logic Flexibility: The onboard jumpers allow you to switch the output between High Level (Pull-up) or Low Level (Pull-down), making it compatible with both NPN and PNP logic styles.
High-Speed Switching: Optimized for suppressing electromagnetic interference (EMI) in noisy environments like motor control or relay driving.
Independent Channels: Each channel is isolated from the others, allowing you to control different voltage levels (e.g., 12V and 24V) on the same board
