#2728: 24V 30A 1-Channel Relay Module with Optocoupler H/L Level Triger


A 24V 30A 1-channel relay module with optocoupler is an electronic device that is used to control high-power electrical devices, such as motors, lights, or appliances. It consists of a relay, a control circuit, and a user interface, and is typically used to switch electrical devices on or off remotely, or to switch between multiple devices. The module is equipped with an optocoupler, which is an electronic component that uses an optical coupling mechanism to isolate the control circuit from the load being controlled. This can help to reduce electrical noise and interference, and can improve the reliability and safety of the system. The module is typically triggered by a low-power control signal, such as a voltage from a microcontroller or a switch. The H/L-trigger version of the module can be triggered by either a high or low level control signal.
