A relay is an electrically operated switch. It consists of a coil of wire that is surrounded by a movable iron core. When an electric current is passed through the coil, it creates a magnetic field that moves the iron core. This movement allows the relay to open or close a circuit, which can be used to control electrical devices or systems. The SMIH-05VDC-SL-C relay is a 5V DC relay, which means that it is activated by a 5V DC voltage. It has a maximum current handling capacity of 16 amps and a maximum voltage rating of 250V AC (Alternating Current). This relay is typically used in low voltage DC control systems to switch AC loads. It is important to note that the relay should not be used to switch DC loads or voltages above its rated values.
