DC 12V Switch Delay-Relay Module with Adjustable Delay Time 0~25 Second Signal Triggering Switch Module

Introducing the DC 12V Switch Delay-Relay Module with Adjustable Delay Time, spanning from 0 to 25 seconds! This module, built upon the NE555 Timer IC’s high-performance timing CPU design, features a power indicator LED and switch trigger timing indication LEDs, offering precise timing control from microseconds to extended hours.

Ideal for vehicle equipment applications, it prevents accidental ignition and safeguards components against sudden high currents.

Operating as a monostable generator based on the NE555 integrated circuit, it allows for adjustable delay times, either via the potentiometer or by modifying the capacitance. Additionally, it’s capable of controlling devices below 220V/10A.

The NE555 chip ensures stability and accuracy in generating time delays or oscillations. It comes with extra terminals for triggering or resetting as needed. In time delay mode, timing is meticulously managed by an external resistor and capacitor. For a stable operation as an oscillator, precise control over free-running frequency and duty cycle is achieved with two external resistors and one capacitor.

This versatile module can be triggered and reset on falling waveforms, with the output circuit capable of sourcing or sinking up to 200mA or driving TTL circuits.
