5 Minutes Timer Relay Circuit with IC CD4093B

5 minutes timer delay using cd4093 circuit

This delay timer is a model for the simple circuit. It is the nature of delays, all electrical devices. In the period of 5 minutes.

You can adorn the end of time. If the circuit uses digital IC CD4093 simply too many. And the use of relay driver transistors.

It leads to a change in the situation with electricity or the electric charge of the equipment is. In our electronic circuit used that simple. May are not the problem of the lot. For LED1 to show in animal nutrition nutrition on the circuit. Simply press the user-friendliness S1 easy to use.

Timing = 0.7 C1 x R1

Note.  that R1 has a value of 1M with S1 switch start at position “2″ .This equates to just short of 300 seconds for each position of S1. C1 and R1 through R2 may be changed for different timing periods. The output current from Pin 3 of the timer, is amplified by Q1 (N3904) and used to drive a relay.
