Relay Module (2 Channels - 24V) magnet Propagation Delay Time: 100 ns

Propagation Delay Time: 100 ns at 2V / 17 ns at 6V at 25°C

which means that it will buzz at a predefined frequency (2300 ±300 Hz) on its own even when you just apply steady DC power

Relay Module (2 Channels - 24V) magnet Propagation Delay Time: 100 nsIntroduction : It is a 2 channel relay board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc. It is also able to control various appliances and other equipment with large current. used where it is necessary to control a circuit by a low power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal.
