Yetaida 2 Channel DC 5V Relay Module with Optocoupler Control Board and Indicator Light, Development Board Accessories Relays, Suport High Low Level

【Dual Channel Precision Control】With our compact 5V DC relay module, it is easy to manage two independent circuits. Relay control module are highly suitable for automation projects, robots, or IoT devices that require synchronous switching without cross interference between channels. 【Super Functional】The low power consumption of the relay module (15-20mA per channel) ensures compatibility with breadboards and portable power solutions. The relays adopts optocoupler isolation, which has strong anti-interference performance. 【Industrial Grade Safety】Built-in optocoupler isolation protects sensitive control circuits from voltage spikes, while flame-retardant PCBs and screw-terminal blocks meet standards. There are 4 fixing screw holes around the relay board, with a diameter of 3.1mm, which are convenient for installation and fixation. Perfect for garage door openers or smart light systems. 【With Indicator Light】The LED indicator lights of each channel of the 5v relay module provide real-time relay activation feedback. Very convenient for electromechanical operations used for educational purposes in classrooms or maker studios. 【5v Relay Module】The relay can operate at ultra-low 5V DC (15mA/channel) and is compatible with solar systems and USB battery packs. Including Python/C++code examples for rapid prototyping.
