The 5V Relay Module controls electrical loads with a single relay, an SRD-05VDC-SL-C model. It operates at 5V and switches loads up to 10A at 250VAC or 30VDC using a microcontroller signal. The module uses a transistor to drive the relay coil with a 3.3-5V input and draws 70-80mA when active. It connects to Arduino circuits for automation and prototyping tasks.

The relay is mounted on a small PCB, approximately 34mm x 26mm, with a three-pin input (VCC, GND, signal) for the control circuit. It provides output terminals (COM, NO, NC) for load connections. It has no jumper to set the trigger mode to high or low, but it has an LED that shows the relay status. The PCB design supports stable operation with a relay life exceeding 10 million cycles at low loads. This module can be used to switch motors, lights, and other appliances in electronic circuits.
