Because of that, many people tend to turn on big energy consumers after midnight, when electricity is cheaper. Logic Families – Wikimedia Commons ; Aug 11, Email Required, but never shown.

Discrete logic gates, flip-flops or anything else which doesn’t need a programmer is acceptable for me. The PLC has 6 inputs and 4 outputs. Doing a 74os162 like this is very easy to do on a very cheap micro since you don’t need it to do anything special. It looks promising to me. We noticed that many new machines have a delayed start option which would be very useful because it would be possible to fill the machine and program it and it would start working by itself during cheaper time.

There are lots of timers that are used to turn lights on and off — they have a switched v outlet in the US. Are there any special considerations for circuits which are going to vibrate?

Who could help me? If I were you I would consider repurposing a kitchen timer or an alarm clock. I had the PLC around from another project.

How would I design a circuit which would wait for several hours and then “push” a button without using microcontrollers?

Mount it straight into the control panel plate of the washing machine Actually I never would have thought of finding a useful purpose for my stack of alarm clocks which I never used.

No need to undercomplicate things just because you are using an off-the-shelf long delay timer. This planar stripe MOSFET has better characteristics, such as fast switching time, low on resistance, low gate charge and excellent avalanche characteristics.

Anyway that’s not yet the problematic part for me. PDF generated using the open source mwlib toolkit. I’m thinking that the button could be replaced by a transistor or some sort of normally off relay.

The datashret would have very low frequency say 2Hz if possible and the counter would send signals to a device which would respond when counter reaches a certain number say after 18 seconds.

Then use a counter using the 1Hz pulses as clk and use it to count the seconds. Communications Interface are available and can be downloaded with the. I’ll take it into consideration. While it definitely wouldn’t be as educational as making a circuit from scratch, it would quickly solve my problem.

It is a free download and can be used as a layout Hitachi Asia Hong Kong Ltd.

I know you specifically said that you did not want to use a microcontroller, but I think you should consider taking the plunge into the microcontroller world. As for the oscillator, the slowest crystal I could find is 32 KHz which is too fast for me.

JeffV 1 5 One of my friends needs a new laundry washing machine, so I went browsing with her. Hitachi bears no responsibility for failure or damage when used. Have it send you an SMS? No registered users and 9 guests. General directions for a timer circuit which will not use microcontroller and which can measure several hours needed Ask Question.

Set the off time on the timer as close to the start time to release the relay.
