Timer Module Circuit Diagram
The multi-functional Timer delay module is a revolutionary circuit with many commonly used timer delay functions. It is perfect for many applications from hobbies to industrial controls. The timer has more than thirty different timing Timer's wiring diagram 3.1 Connecting timer
Sometimes you may need ready-made hardware to set up a simple timer to help you control something at the right time. No wonder, Chinese electronics have many instant solutions for that, the simplest of which is the 555-timer module. As usual, there are many variants, but this post is about a cheap quotNE555 0-10S Delay Timer Relayquot module I came across recently.

Adjustable ON OFF Timerusing 555 astable mode In this circuit a timer with cyclic on off operations is designed. This circuit uses very basic components like 555 timer and 4017 counter. These on off intervals can be adjusted by varying the 555 timer output and number of counter outputs. Let us discuss in detail about this circuit. Circuit Diagram
The IC 555 timer circuits rely on three 5K resistors to produce a voltage divider at pins 1 and 8. The circuit diagram above is for a one-minute timer based on the IC 555. To get varying times, all you have to do is adjust the values of the resistor R1. Additionally, the timer is in a mono-stable mode and starts timing when you power the circuit.
To understand how an adjustable delay timer relay module circuit works, you can carefully observe the functional block diagram and pin function descriptions of the 555 IC published below.

Circuit Description. As shown in the diagram, the IC 555 is wired as an astable clock generator circuit. This circuit forms the basic time interval generator stage. The clock pulses are fed to pin 14 of IC2 7490 which is a divide-by-10 decade counter, and it divides the clocks from the IC 555 by 10, and the output is generated at its pin11.

The 555 Timer, designed by Hans Camenzind in 1971, can be found in many electronic devices starting from toys and kitchen appliances to even a spacecraft. It is a highly stable integrated circuit that can produce accurate time delays and oscillations. The 555 Timer has three operating modes, bistable, monostable and astable mode.
Using a Start Push-Button. The above design could be upgraded with a push-button to facilitate a push button start. This further ensures that the timer shuts off completely in case a power failure occurs while the circuit is operational, which in turn ensures that crucial loads like heater, or geyser are completely turned OFF during such situations.
