Description: 1. A 1-Channel 12V Relay Module with Optocoupler is an electronic switch that safely operates high voltage or current circuits using low voltage signals. This device ensures electrical isolation between controlled circuit and control circuit. 2. Components: The module consists of a single-channel relay, optocoupler, diode, resistor network, and mounting hardware. The optocoupler acts as an interface to electrically isolate the control input from the high voltage output circuit. 3. Operation: When a signal is applied to the control input of the module, it activates the optocoupler which in turn energizes the coil of the relay. This change in state closes or opens the contacts depending on their initial position, thereby connecting or disconnecting the controlled circuit. 4. Versatility: The 12V Relay Module with Optocoupler can be used to switch a wide range of loads, from small incandescent lamps to high-current motors and solenoids, up to the maximum rated voltage and current. 5.
