TN-R-5995 2-channel 12V relay module
TN-R-5995 2-channel 12V relay module for Arduino, Raspberry Pi, and microcontroller control of AC/DC devices.
The TN-R-5995 2-Channel 12V Relay Module is a reliable solution for controlling high-voltage AC or DC devices using low-voltage microcontroller signals. Operating at 12V control voltage, each relay can switch loads safely up to 10A, making it ideal for home automation, robotics, DIY electronics, and industrial control applications.
This module features optocoupler isolation for microcontroller protection, indicator LEDs for status monitoring, and screw terminals for secure wiring. Compatible with Arduino, Raspberry Pi, ESP32, ESP8266, and other microcontrollers, it provides an easy and safe way to control lights, fans, motors, and other appliances.
