The 12V Dual-Channel Relay Module with Optocoupler Isolation is designed to allow microcontrollers, such as Arduino, Raspberry Pi, or other platforms, to safely control high-voltage devices. This module features two relays, each capable of switching AC or DC loads up to 12V, making it ideal for a variety of applications like automotive, home automation, or industrial control systems.
Equipped with optocouplers (light coupling), the module provides electrical isolation between the low-voltage control side (the microcontroller) and the high-voltage load, protecting your sensitive electronics from voltage spikes and other electrical issues. The relays are controlled by logic-level signals, making it compatible with both 3.3V and 5V microcontrollers.
 
Features:
High-current relay rated at 10A@250VAC / 10A@30VDC.
Capable of controlling both AC and DC appliances, including solenoids, motors, lights, fans, and more.
High-quality screw terminals (C, NC, NO) for easy and quick connections.
Includes a freewheeling diode to protect your microcontroller.
Input signal pin connected to a Burg stick for easy access.
LED status indicators to show the relay ON/OFF status.
Mounting holes provided for secure installation.
Signal input requires a high-level signal to trigger the relay, allowing easy conduction between common and often contacts.
The relay can directly control various devices and loads.
Features one Normally Open (NO) and one Normally Closed (NC) contact.
Convenient Blue KF301 terminal blocks for easier wiring.
Package Includes:
1 x 12V Dual Channel Relay Module with Optocoupler.
