Schematic for Time Delay RelayThis article is a time delay relay circuit diagram. The principle is simple and very practical. Want more thoroughly grasp the principle, you should understand and be familiar with the major components of the circuit, such as: 1n914 . When activated by pressing a button, the time delay relay to activate a load at the specified time. This time is adjustable to any place you want just by changing the resistance value and/or capacitor. The current capacity of the circuit is limited only by what you decide to use relay. Calculation time delay, using the equation of C1 R1 * * 0.85 = T, the value of R1 in ohms, the value of C1 R1 at the university of Florida, and T C1 is time delay in seconds. S1 may be changed into a NPN transistor circuit can be computer, so other circuits, etc. Most any 6 v relay K1 will work. If you use a large, relay, you and I need to add a transistor output circuit to drive the greater the load.
