16CH-RELAY-OPTO-12V

The 16CH 12V Relay Module with Opto-Isolation is a highly reliable, multi-channel relay board designed for industrial automation, home automation, and electronic projects. Featuring 16 individual 12V relays, each channel is optically isolated to protect your microcontroller from voltage spikes and electrical noise.

This module is ideal for controlling high-power devices such as lamps, motors, fans, and solenoids using low-power microcontroller signals. It comes with screw terminals for easy wiring and supports TTL logic input from Arduino, Raspberry Pi, ESP32, and other development boards.

Key Features:

• 16 independent 12V relays with LED indicators

• Opto-isolated channels for enhanced protection

• Supports TTL logic control (3.3V–5V microcontrollers)

• Easy to mount with screw terminals for devices

• Ideal for Arduino, Raspberry Pi, ESP32, and other MCU projects

• Compact and durable PCB design for reliable long-term operation

• Perfect for industrial automation, smart home systems, and DIY electronics projects
