At the same time, the module comes with two positioning holes with a diameter of 3mm, which is convenient for you to fix the module to other deviceswhen the s signal terminal is set to a high level, the relay is turned on, the com terminal and the nc terminal of the relay are disconnected, and the com terminal and the no terminal are connected; when the s signal terminal is set to a low level, the relay is closed, the relay com terminal and the nc terminal are connected, and the com terminal is connectedwhen controlling, we connect gnd to the mcu gnd, vcc to the mcu 33vrated current: 50--120macoil impedance: 25--60ωmechanical life: 100,000 times under no loadelectrical life: 3a/250vac cosφ=1, 1specifications:working voltage: dc 3introduce:this is a commonly used single-channel relay module, which mainly uses hk4100f-dc 3v-shc relay components3v, and s to the mcu digital portwhen the relay is not connected to the control signal, the com terminal and the nc terminal are connected, and the com terminal and the no terminal are disconnectedit is usually used in automatic control circuits, and it is actually an "automatic switch" that uses a small current to control the operation of a large currentterminal and no terminal are disconnectedthe relay has 3 green binding posts for external circuits, which are no com and nc terminals (screen printing on the back)therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit
