Product details
This relay module provides one electromechanical relay channel, driven at 5 V DC. It does not include an optocoupler, so the control logic (Arduino / MCU) is directly interfaced to the relay-drive transistor. It allows you to control a single load (AC or DC) up to 10 A using a microcontroller output pin. It includes status LED(s), screw-terminal output (COM / NO / NC), and pin header (VCC / GND / IN) for control. Compact and simple design, suitable for DIY, automation, embedded systems or prototypes where electrical isolation is not required.
