Timer Terminology

[ABLE1]

Hello All,

I have been reading this newsgroup for some time, mostly for my own
edification and mild amusement/wonderment. Thanks to all for their
on topic comments of the past few years.

I now have a project that I am sure somebody in here can lend some
insight. I am looking for a timer board and it would be helpful if I
had the correct terminology so it would make my search easier.

The timer needs the following criteria.

Upon power up (9-12vdc) it would start to time out for an adjustable
about of seconds say 1-600. At the end of the cycle it would energize
the relay for a period of 1-2 seconds (maybe adjustable) and then reset
and start a new cycle and do this continuously until power is removed.

An alternative timer would be one that could some how be random in its
timing duration but would only energize the relay for a 1-2 seconds and
then choose another random time for cycle. A pot adjustment would allow
for a maximum random number. This I think will be much harder to find
in a commercially made item, maybe possible in a custom made board of
some sort.

My main quest is for the proper terminology but if anyone know of a
particular mfg. model they would like to share that would be great.

I hope all of that make sense to some degree.

Thanks in advance for any insight.

Les

That sounds like a job for a microcontroller like the Arduino Uno, especially for the random duration part.

google on 555 timer. Just what you need for just a few cents.

Then go for the arduino. Can be had on ebay for ~$7. Use an opto-relay from the Arduino output to energize the relay, I use the LCA710. Depending on the need, you might not need the relay, just the LCA710, it's a 1 amp SPDT MOS solid state relay.

That looks very interesting if I was 30 to 40 years younger and really
had the time to investigate and learn something new. However,that is
not to be at this point in my life.

My quest stands as typed.

** Really ?

What the hell is this for ?

Cos it better be *VERY* important - so you are happy to pay a professional to build one for you.

This NG is a compleety wrong place for that.

A single 8 pin (~$2) Picaxe controller can do that and is programmed
in Basic. There's a great forum for it and they will give you all the
help you need. Need more I/O and they have versions with 14,18, 40
pins.

I've got them working cameras, regulating the elements on my electric
range, working the computer fan, monitoring temperatures in four
areas, working beacon strobes, replacing the shot controller on a
window AC, and the overdrive on my truck's transmission. and I ain't
no kind of programming wizard...

sounds like you aren't willing to put out any effort

I grew up with vacuum toobes and still enjoy learning and tinkering.

I bet some Rube Goldberg contraption with synchronous motors, cam
operated switches, and other doo-dads could do what you want too.

You're on the wrong way. Timers like the ones you mentioned are not
described by their behaviour but by their usage. "Kitchen timer" or
"cooking timer" for example. So if you name it that way, you may find
something usefull. Try "programmable timer" for instance. FAIK the
timers you want, are not off the shelf items. So you may have to do some
work or have to pay someone else to do it for you. If you choose for the
last option you will have to provide more details. Available power and
load are among them.

I don't think he is going to find a ready built solution because of the need
for a random delay. I've never seen a device that would supply this and
I've never heard of a need for a random delay timer. I think if he is not
willing to do any work in building one, he won't find it.

If it's the only electronics in your system, and you want it to mount
conveniently, a PLC is a slam-dunk. Otherwise, the Arduino suggestion is
probably spot-on.

I would first like to thank all that have contributed to this thread.

As most have missed (or maybe not) I was looking for proper terminology
for timer features. Hence the Subject Line.

I did not go into great detail since most would not have read the
massive amount of words, sentences, paragraphs and would have only
gleaned out what they wanted by scanning the novel.

As for the "random timer" thought it was just a whim, that I should have
not been included since for my application it could be achieved with 2
or 3 timers triggering the same input at different times which will work
just fine. So please disregard that point.

I am really not looking for someone to custom build a timer for me. I
was hoping to get the right terminology so I am not searching for the
wrong thing. I would really like a off the shelf unit that would do
what I want. The term "flip-flop" or "on delay" or "off delay", will
not meet the desire of starting a delay but when triggered will only
energize for 1-2 seconds and then start again.

That is the terminology I was and still am looking for. Programmable is
only part of the answer.

I am 70+ and yes, I learn something every day as well. But to spend the
time required to learn how to setup and program a magic device for just
one project is a little more than I think necessary with all the other
stuff I already have on my plate. But I digress.................

I am guessing maybe a 9-12vdc input programmable dual rate delay timer
with built in relay type thingie that will work between 1 and 600
seconds as a minimum. I was hoping there was some terms that could be
used and maybe what I have learned here is that "programmable timer" is
as good as it is going to get.

Oh, and what I am going to do with this timer thingie should be of
little importance. But, suffice it to say that it is an attempt to
convince a bunch of canines to make peace with the world and shut up.

Again, thanks for the input.

Have a good rest of the weekend.

in a commercially made item, maybe possible in a custom made board of
some sort.

My main quest is for the proper terminology but if anyone know of a
particular mfg. model they would like to share that would be great.

I hope all of that make sense to some degree.

Thanks in advance for any insight.

Then go for the arduino. Can be had on ebay for ~$7. Use an opto-relay
from the Arduino output to energize the relay, I use the LCA710. Depending
on the need, you might not need the relay, just the LCA710, it's a 1 amp
SPDT MOS solid state relay.


That looks very interesting if I was 30 to 40 years younger and really had
the time to investigate and learn something new. However,that is not to be
at this point in my life.

My quest stands as typed.

At a junkyard, you could cannibalize an old oven or microvave oven for its timer.
(unless you're infirm and use a walker or are in a wheelchair, then you could order one of those 120v15a plus 9r minus outdoor security lights with the alternating feature capability. Ask around at Lowe's, Home Depot, HF, etc... Or one of those '24 hour lighting timers')

Hello All,

I have been reading this newsgroup for some time, mostly for my own
edification and mild amusement/wonderment. Thanks to all for their
on topic comments of the past few years.

I now have a project that I am sure somebody in here can lend some
insight. I am looking for a timer board and it would be helpful if I
had the correct terminology so it would make my search easier.

The timer needs the following criteria.

Upon power up (9-12vdc) it would start to time out for an adjustable
about of seconds say 1-600. At the end of the cycle it would energize
the relay for a period of 1-2 seconds (maybe adjustable) and then reset
and start a new cycle and do this continuously until power is removed.

An alternative timer would be one that could some how be random in its
timing duration but would only energize the relay for a 1-2 seconds and
then choose another random time for cycle. A pot adjustment would allow
for a maximum random number. This I think will be much harder to find
in a commercially made item, maybe possible in a custom made board of
some sort.

On Ebay:
"Digital LED Display Infinite Cycle Loop Delay Timer Switch ON/OFF Relay
Module"

http://www.ebay.com/itm/Digital-LED-Display-Infinite-Cycle-Loop-Delay-Timer-Switch-ON-OFF-Relay-Module-/182275672085?var=&hash=item2a707a0815:m:mNa55OkEUIE3hlaBF2XVwkw

$4.98 with free shipping. Does what you described in your first
criteria paragraph; does not do random.

Scroll down on the ebay page for the instructions. (They
can be a bit confusing.) Here's a head start.
First, power the module on. The use the buttons to set
the following values in each step:

Step 2: Function P4
Step 3: T1 Time Unit -2
Step 4: T1 Time 03 (3 minutes)
Step 5: T2 Time Unit -1
Step 6: T2 Time 02 (2 seconds)
Step 7: Cycle Times 0 (infinite loop)

For the Time Units in steps 3 and 5, I don't remember
if the minus sign was displayed or not.

Thanks Ed,

Did you notice that it is Free Shipping at that price for Hong Kong??

I found that to after some searching. However, I decided on a USA
supplier with a slightly different unit with Free Shipping for a couple
of $'s additional. But that is OK with me.

Will be delivered by Friday and already programmed for my task.

Thanks again!!!

Les

we're designers and tinkerers here, not your personal shopper. I think
most here wouldn't buy that sort of thing pre-made.


off the shelf, some sort of PLC I guess, if ypu want easy to program
lego mindstorms perhaps...
