The trigger delay can keep the signal outputs by the input module for a certain period of time.
The trigger delay is based on an RC circuit, an RC circuit (resistor-capacitor circuit) is an electric circuit composed of resistors and capacitor, which is a way to create a time delay in your circuit. The RC delay circuit works on the principle of the RC charging and discharging. We know that the capacitor is able to store electrical energy they act like small batteries and can store or release the energy as required.
1. When power for the delay module, the capacitor will be charged, and when the voltage of the capacitor reaches a certain value, the capacitor will discharge. The charging and discharging of the energy of a capacitor takes a certain time that we called time delay.
Use the trigger delay behind an input module, then see how long it will last the input signal.
The adjustable potentiometer on the module allows you to adjust the delay time. Rotate the potentiometer clockwise, the delay time will last longer. Rotate the potentiometer counterclockwise, the delay time becomes shorter.
