First section of this circuit is time delay elements such as voltage divider resistor series and two electrolytic capacitor and Second section is Relay with indicator LED.. Resistor R1, potentiometer and R2 connected in series and across to the DC input supply, output of variable resistor (potentiometer) is connected to the C1 capacitor and reverse biased Zener diode
Hence, it is safe to provide a time delay before giving the power to device. This prevents the disastrous effects of voltage spikes or input surge currents. The aim of this project is to demonstrate the functioning of a time delay relay. Time Delay Relay can provide a short delay after power is turned on and before switching on the device. we are going to show you how to make a Time delay relay circuit using a 555 timer IC. This circuit is able to trigger the relay from a few seconds to a few m The sensors are npn i.e. when the wheel of an engine passes the sensor grounds a relay coil, the other end being connected to +12v. I am looking for a circuit to delay the on time of the relay for say 1sec. with an output from the sensor going from 12v to zero to activate. All the above use circuits use plus volts to trigger.

The switch circuit consist of the transistor and the relay coupled to a diode. Once the charge from the capacitor is still preserved with time,when the push button is released,the transistor is switch on as a result of the electric field,and as such, the transistor the transistor activates the relay,which is used to drive any electric load
Learn how to build your own time-delay relay circuit with this easy-to-follow DIY tutorial. We'll guide you through the entire process, from selecting the ri The relay switches the connected AC/DC load. Testing Procedure: Power Up: Connect a 5V-9V supply. Ensure the LED and relay remain off initially. Trigger Test: Press the button. The LED should illuminate, and the relay should click, staying active for the set time. Adjust Timing: Rotate VR1 to test the delay range. Use a stopwatch to verify
