Time-delay Relays | Electromechanical Relays | Electronics ...

Newer designs of time-delay relays use electronic circuits with resistor-capacitor (RC) networks to generate a time delay, then energize a normal (instantaneous) electromechanical relay coil with the electronic circuit’s output. The electronic-timer relays are more versatile than the older, mechanical models, and less prone to failure.

Timer Circuits | Digital Circuits Worksheets

A passive differentiator network between each 555 timer ensures that only a brief negative-going pulse is sent to the trigger terminal of the next timer from the output terminal of the one before it. Follow-up question: when timer circuits are cascaded like this, do their time delays add or multiply to make the total delay time? Be sure to ...

555 Timer tutorial - Jameco Electronics

Figure 2 shows the basic 555 timer monostable circuit. Figure 2: Basic 555 monostable multivibrator circuit. Referring to the timing diagram in figure 3, a low voltage pulse applied to the trigger input (pin 2) causes the output voltage at pin 3 to go from low to high. The values of R1 and C1 determine how long the output will remain high.

Automatically Repeating Interval-Timer Circuit

Printed circuit board - Wikipedia

Printed circuit boards were introduced to reduce the size, weight, and cost of parts of the circuitry. In 1960, a small consumer radio receiver might be built with all its circuitry on one circuit board, but a TV set would probably contain one or more circuit boards.
