The 1-channel 12V relay module lets you switch high-power loads such as lamps, pumps, fans and solenoid valves in response to a signal from a microcontroller or another control circuit. The board carries a JQC-3FF-S-Z relay with a 12V DC coil, a transistor control switch, a protection diode and two LEDs: PWR (power) and SW (relay state). The load connects to a 3-pin screw terminal block (NO, COM, NC), and control is provided through a pin header with VCC, GND and IN. The module is convenient wherever the system is already powered from 12V: automotive electronics, solar installations, aquariums, greenhouses and smart home projects.
