The 12V 4-Channel Relay Module with Opto-Isolated Input is a powerful and safe switching solution designed for high-voltage and high-current control applications. Each channel features an opto-isolated input, protecting your microcontroller from voltage spikes and electrical noise. With AC250V 10A and DC30V 10A output capacity, this module can control lights, motors, and appliances with ease.
The LED indicators provide clear visibility of the relay status, and the standard interface allows direct control from various microcontrollers like Arduino, AVR, PIC, and ARM-based boards. Whether you’re working on home automation, robotics, or industrial control systems, this relay module delivers reliable and efficient performance.
Q1: Can this module control 220V AC appliances?
A1: Yes, it supports AC loads up to 250V 10A, making it suitable for 220V AC devices.
Q2: Do I need additional components to connect it to an Arduino?
A2: No, the module has a standard interface and works directly with Arduino and other microcontrollers.
Q3: What does opto-isolation mean?
A3: Opto-isolation protects your microcontroller by using light signals to separate high-voltage and low-voltage sides, preventing voltage spikes and interference.
Q4: How do I know if a relay is active?
A4: Each channel has an LED indicator, which lights up when the corresponding relay is activated.
Q5: What kind of devices can I control with this module?
A5: You can control AC devices like lights, fans, and home appliances, or DC devices like motors, pumps, and solenoids.
