The 16-Channel Relay Module is a control board with 16 independent relay outputs, designed to switch loads on and off in response to a control signal ranging from 5V to 40V. This wide input range makes it flexible enough to work with a variety of controllers, microcontrollers, and automation boards, so it suits hobbyists, makers, irrigation projects, and small automation setups alike. Whether you are switching pumps, solenoid valves, lights, or fans, the 16 separate channels let you manage several devices from a single module.
