DC3V-6V Электродвигатель с пластиковым двигателем TT колесо для шин двухвальный

Wide voltage 5V-30V trigger delay relay module timer module delay switch Wide voltage 5V-30V trigger delay relay module timer module delay conduction delay switch button Module Highlights: The time can be adjusted by the potentiometer to meet your use in most occasions. With MicroUSB 5.0V power input, it is very convenient to use. 5--30V supply voltage. There are two trigger modes: external trigger and onboard button. With relay pull-in indicator light. Strong anti-interference ability, the relay will not malfunction under various disturbances, suitable for industrial control. Module Features: 1. Working voltage: any voltage between 5-30V wide voltage, two power supply interfaces of MicroUSB and welding terminal 2. Working mode: After supplying power to the module, the status of the output terminal of the module is: normally open (NO) and common terminal (COM) are disconnected, and normally closed (NC) and common terminal (COM) are connected. Give a low pulse signal to the external trigger terminal (TRIG), or touch the trigger button, the relay will pick up and the working indicator will be on. The normally closed (NC) is disconnected from the common terminal (COM). After 0-24 seconds (this time can be adjusted according to your needs), the relay is disconnected, and the relay returns to the state before the trigger. 3. The time can be adjusted by the potentiometer, the default is 0-24 seconds. If it takes longer, you can replace the larger capacitor (C2) or potentiometer yourself. Delay time formula: T=1.1RC. For example: capacitor 22uf resistance 1M then T=1.1*0.000022*1000000=24.2 seconds. 4. With relay pull-in indicator light. 5. The module can control: 10A 250VAC (AC), 10A 30VDC (DC) loads below. 6. With relay freewheeling protection. 7. The signal end of the module is designed with a pull-up and filter circuit, which has strong anti-interference ability and is suitable for industrial control. Many manufacturers have added optocouplers for isolation, but the module is not isolated from the ground of the trigger signal, which does not play an anti-interference effect. After the test, it is found that the stability of the trigger terminal can be improved to resist interference. Whether the module is in an electromagnetic interference environment or at the moment when the module is turned on and off, the relay will not cause malfunction. 8. Size: 5.4*1.9*1.8cm (length*width*height) 9. Weight: 16g Applications: 1. Anti-theft alarm delay, building sound and light control light switch, etc. 2. The on-board equipment is connected with a delay time to prevent the vehicle equipment from being burnt due to excessive current when the car is on fire. 3. When it is necessary to have a sequential start, prevent multiple devices from starting at the same time and the current is too large to burn the electrical appliances.
