5V-30V Micro USB Power Adjustable Delay Relay Timer Control Module Trigger Delay Switch
Wide voltage 5V-30V trigger delay relay module timer module delay switch Wide voltage 5V-30V trigger delay relay module timer module delay on delay switch
Module highlights:
The time can be adjusted by the potentiometer to meet your most occasions. With MicroUSB 5.0V power input, it is very convenient to use. 5--30V power supply voltage. External trigger and on-board key trigger. With relay pull-in indicator. Strong anti-interference ability, the relay will not malfunction under various interference, suitable for industrial control.
Module characteristics:
1. Working voltage: any voltage between 5-30V wide, MicroUSB and welding terminal power supply interface 2. Working mode: After supplying power to the module, the state of the output terminal of the module is: normally open (NO) is disconnected from the common terminal (COM), and normally closed (NC) is connected with the common terminal (COM). Give a low-pulse signal at the external trigger terminal (TRIG) or touch the trigger button, the relay sucks and the work indicator lights up. At this time, the status of the relay output terminal is: normally open (NO) and the common terminal (COM) are conducting, 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 triggering. 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 by yourself. Delay time formula: T = 1.1RC. For example: if the capacitance is 22uf and the resistance is 1M, then T = 1.1 * 0.000022 * 1000000 = 24.2 seconds. 4. With relay pull-in indicator. 5. The module can control: 10A 250VAC (AC), 10A 30VDC (DC) load. 6. With relay continuous current 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 provide anti-interference effect. After testing, it is found that the stability of the trigger terminal can be improved to resist interference. No matter the module is in an electromagnetic interference environment or when the module is powered on and off, the relay will not 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. On-time delay of on-board equipment prevents excessive current from burning the vehicle equipment when the vehicle is on fire. 3. Sequential start-up is required to prevent multiple devices from starting at the same time when the current is too large to burn down the appliance.
