This 4-piece set of DC 12V relay modules is designed for versatility and reliability in controlling electronic devices. Each module operates at a working voltage of DC 12V and features a high efficiency with quick action and release times of under 10ms and 5ms, respectively. This allows you to automate your systems effectively without noticeable delays.
The relay board supports a normally opened (NO) configuration, which means that when the relay is turned off, the NO pin is not connected to the common (COM) pin. When activated, however, the NO pin connects to the COM pin, allowing power to flow. For applications where devices need a direct connection upon default, the normally closed (NC) pin is available, ensuring safety by connecting to the COM pin when the relay is off.
Each module has a user-friendly interface design, with all connections made via terminal wiring leads. The trigger pin allows for high or low-level signal connections, making it adaptable for various control needs in your projects. A power indicator (green) and relay status indicator (red) are included to provide real-time feedback on the module’s operation.
The package contains 4 pieces of the 12V relay module, each supporting high and low level triggering. Whether you're working on DIY electronics projects or more sophisticated automation tasks, this relay module set ensures reliable performance and efficiency.
