The 5 V relay module enables safe switching of high-voltage loads via microcontroller logic. Its compact size, mechanical durability, and wide operating conditions make it a versatile choice for automation, lighting control, and DIY electronics projects.
This 1-channel relay module features an SRD-5VDC-SL-C relay that allows control of mains-powered devices up to 250 V AC or 125 V DC using a low-voltage digital signal from a microcontroller such as Arduino. It includes 2.54 mm pitch header pins: VCC, GND, and IN. The relay is activated by a LOW signal, which closes the COM–NO contacts and lights up a green LED indicator.
