12V 2-Channel Relay Module with Optocoupler Isolation
The 12V 2-Channel Relay Module with Optocoupler Isolation is a reliable switching solution designed for safely controlling high-voltage AC or DC loads using low-voltage microcontrollers. Operating on a 12V DC supply, this dual-channel relay module features optocoupler isolation to electrically separate the control circuit from the load circuit, protecting sensitive electronics from voltage spikes and electrical noise.
Built on a high-quality FR-4 PCB using an advanced SMT manufacturing process, the module delivers stable and long-lasting performance. It includes power and relay status LEDs for easy monitoring, while COM (Common), NO (Normally Open), and NC (Normally Closed) screw terminals simplify wiring and installation.
Compatible with Arduino, ESP32, Raspberry Pi, AVR, PIC, ARM, and other development boards, this 12V relay module is an excellent choice for home automation, robotics, industrial automation, IoT applications, and remote switching projects.
Features:
- High-current relay: 10A at 250VAC and 10A @ 30VDC.
- Controls both AC and DC equipment (such as motors and lights).
- Screw terminals of high quality (C, NC, NO) allow for easy connection.
- A freewheeling diode for microcontroller protection.
- Input pin is available via Burg stick.
- LED indications show whether the relay is turned on or off.
- Mounting holes are included.
- A relay regulates a variety of loads and equipment.
- For convenience, use the blue KF301 terminal.
