This is the 12V variant of the DC 12V Relay with Adjustable Delay Time Signal Triggering Switch Module in Relay Modules. Available at ₹116.82 (₹99.00 + GST) with free shipping across India.
Description:
The DC 12V Switch Delay Relay Module features an adjustable delay time of 0 to 25 seconds and is based on the NE555 Timer IC, designed for high-performance timing applications. It includes a power indicator LED and timing indication LEDs for clear visual feedback.
This versatile module is suitable for various applications, including vehicle equipment, where it can delay ignition to prevent high surge currents that may damage components.
Operating as a monostable generator, the NE555 integrated circuit allows for adjustable delay times from 0 to 10 seconds, which can be configured using a potentiometer or by changing the capacitor values. It can control devices up to 220V and 10A.
The NE555 is renowned for its stability in generating accurate time delays and oscillations. It provides terminals for triggering or resetting as needed. In delay mode, timing is precisely managed by an external resistor and capacitor. For stable oscillation, the free-running frequency and duty cycle are controlled by two external resistors and one capacitor. The circuit can be triggered and reset with falling waveforms, and the output can source or sink up to 200mA, making it compatible with TTL circuits.
Features:
- Precision Pulse Generation / Timing.
- Adjustable Duty Cycle.
- Monostable Operation.
- Standby no power consumption.
- Excellent temperature stability 0.005% / oC.
- Countless Application and Information Sources.
- Module supplies a diode with an anti-power reverse connection.
- Time can be adjusted by a potentiometer, the default is 0-25 seconds.
- Module signal side design has optocoupler isolation, anti-interference ability can adapt to the high-low level two kinds of control signal application, suitable for industrial control.
- Module can be triggered repeatedly (such as setting delay 10S in a 10S trigger delay occur again within the trigger action, in action again re 10S delay, with delay, in the end, is not the last trigger prevail, back and delay 10S, until it reaches the delay time to trigger the whole process time delay. After the delay, it is triggered again and again.
Applications:
- Can be used for robots
- Automotive lights
- Intelligent product development
- Automation equipment
- PLC development
- Smart home
- Anti-theft alarm
- Electronic development and so on
