The 8-Channel 12V Relay Module with Optocoupler is a high-quality switching board designed for controlling multiple AC and DC devices safely.  Each of the 8 relays can handle high-power loads independently, making it ideal for home automation, industrial control, robotics, and smart device projects.

Features:

1. Built-in optocoupler isolation for enhanced safety and noise immunity.
2. Compatible with Arduino, ESP32, STM32, Raspberry Pi, and other controllers.
3. Supports both normally open (NO) and normally closed (NC) contacts.
4. LED indicators for real-time relay status monitoring.
5. Durable PCB design for stable and long-term operation.
6. Low-level trigger input for easy interfacing with microcontrollers.
