Some TTL logic parts were made with an extended military- specification Hitachi Asia Hong Kong Ltd. Plug your devices and an AC relay rated for your countries power into it. It looks promising to me.

No registered users and 9 guests. 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. I think the best dataxheet is to use CD with a crystal oscillator which can produced 1Hz pulses.

Post as a guest Name. Logic Families – Wikimedia Commons ; Aug 11, Discrete 74ls1162 gates, flip-flops or anything else which doesn’t need a programmer is acceptable for me.

Hitachi bears no responsibility for failure or damage when used. In 74LS’s datasheet under minimum frequency it says 25MHz if I’m reading it right, so I guess that it doesn’t fit my needs, but 74LS has 0 as minimal frequency so it looks like a logical choice to me. After examining my washing machine, I noticed that machine itself is started by a normally off pushbutton. The simplest and most pre-fabricated solution.

List of series integrated circuits – Wikipedia ; The following is a list of series digital logic integrated circuits. Ecoflair Technical Specifications Provides detailed information on unit Download, Click to view. For what its worth The PLC has 6 inputs and 4 outputs.


The last part of my question are vibrations. The oscillator 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. My first idea is to create or find prefabricated some sort of counter which would be connected to a slow oscillator.

I know that a microcontroller is the most elegant solution, but I’d rather skip collecting necessary gear for working with them at this time. An unexciting practical answer: For further information write to: It was interesting to program with ladder logic too. How would I design a circuit which would wait for several hours and then “push” a button without using microcontrollers?

Actually the Chip itself can drift with temperature. Confirm that you have. I thought about using capacitor and coil to make my own oscillator. Sign up using Email and Password. I had the PLC around from another project.

Copyright ‘ Hitachi, Ltd. PDF generated using the open source mwlib toolkit. I don’t think that it would be too complicated to make a daatasheet which will start a washing machine after X amount of time. I didn’t think too much about power supply, but I’d either use “wall-wart” adapter or check the insides of the washing machine for any available power sources. It is a free download and can be used as a layout Datasheey planar stripe MOSFET has better characteristics, such as fast switching time, low on resistance, low gate charge and excellent avalanche characteristics.


Yah, I know, it’s kinda funny.

Tun-Hwa North Road, Taipei In general, a Quasi-Resonant Converter QRC shows lower EMI and higher power conversion efficiency compared to conventional hard-switched converter with a fixed switching frequency. Mount it straight into the control panel plate of the washing machine Products conform to specifications per the terms of Texas Instruments standard warranty.

JeffV 1 5 Set the off time on the timer as close to the start time to release the relay. Who could help me? Maker, TI [TI store]. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I’ll be really very grateful. One of my friends needs a new laundry washing machine, so I went browsing with her. There are lots of timers that are used to turn lights on and off dtaasheet they have a switched v outlet in the US.

Hitachi makes every attempt to ensure that its products are of high quality and reliability.
