So, after you broke the broken equipment even more, which repair guy
did they then send it to?

Yer too stupid to do repair work. Matsushita must have booted yer ass
after you messed up too much equipment.

WHO IS 'MEAT PLOW' from Alt.Usenet.Kooks (AUK)?

The obese, abusive, ugly, snaggle-toothed, giant-headed, stalking, gay
'bear' biker retard who likes to surf gay porn sites as 'BlancoBear'
while wearing only assless chaps:

William Malone Griffith, Jr.
(aka Milt, Meat Plow, BlancoBear, Meat@petitmorte.net, Tripp)
308 10th Street NE
North Canton, OH 44720-2023

Meat Plow on a stalking holiday excursion, 15 to 22 Aug 2011:

Nevermind that West Palm Beach, FL is 110 miles (not 60 miles) from
Melbourne, FL.

to make it up to Melbourne (Albatross hit my email) before the 20th

Hmmm... only one and a half days 'visiting friends in West Palm Beach'
(if he was ever there to begin with), and the rest of his time in
Florida spent real-life stalking. He even extended his stay by two
days, so he could get in more stalking.

Meat Plow quotes:
--------------------
Meat Plow, explaining that his computer has no Master Boot Record
because he runs Mandriva 2010, not Windows:
Message-ID: <4v39g0.au.17.9@news.alt.net>
"Wouldn't know, it's been months since I've booted a Windoze OS."

Meat Plow describes his high-powered legal team:
Message-ID: <pan.2011.05.25.00.08.32@emutt.macspoofer.lmao>
"You know i have a legal team who specializes in internet law. And I
won't hesitate to get them in on the action."

Meat Plow losing his connection to reality, insinuating that he's law
enforcement:
Message-ID: <pan.2011.07.02.00.58.38@emutt.macspoofer.lmao>
"I could be LE posing as Meat Plow. It can't be dis-proven."

Meat Plow visits a massage parlor for a Happy Ending massage.
But they refused to give him a Happy Ending his second time there.
That explains why he's gay, he's so repulsive that he can't even PAY
for HAND JOBS from women.

"One time I got a HE, and the 2nd time I didn't. I was asked if I was
there both times and said I was. That's is why I didn't know if I said
something wrong the 2nd time which made me not get a HE."

Well, at least we know what he does with his weekends.

Catherine Griffith = William Malone Griffith, Jr.'s mother

Julia M. Griffith = William Malone Griffith, Jr.'s daughter

Cheri Griffith = Cheryl J. Griffith-Rivera, William Malone Griffith,

Kristy Griffith = Christine H. Griffith-Vick, William Malone Griffith,

Questions yet to be answered:
Who is Justin M. Griffith?

Angela C. Griffith-Warshefski came all the way from Pompano Beach,
Florida to witness and sign MeatPlow's apology letter?

Or did William Malone Griffith, Jr. forge the witness signatures,
which would indicate some level of insincerity in the apology?

If William Malone Griffith, Jr. did indeed forge the witness
signatures, is his family cognizant of him using them in this way?

Who is Deborah Ann Griffith?

Who is Sherri Renee Christie, William D. Christie (age 54) and Lillie

But, in this case, the OP has a relay which isn't dual-rated, but

"yup"?

Strangely, your pretentiously authoritative "yup" seems designed to
denigrate my critique as if you knew you were wrong and tried to
assign the guilt to me.

Again, I'm confused.

If, as you say, it's normal to simply fix holding current to keep from
overheating the coil [by using the impedance of the coil as a current
limiter, once it's closed] then, since the strength of the magnetic
field varies, in an inverse square law kind of way, as a function of
the distance between the pole pieces, there's the very real worry
about the spacing of the pole pieces which will guarantee closure.

By God, maybe, but to us mortals the change in impedance is
serendipitous and all we can do with it is to work out the "must
close" to "must open" hysteresis.

Are you saying that a variable current in the coil won't react against

Well, I'm certainly not going to spend any portion of the rest of my
life searching for that reclusive gem but, in the same vein, I invite
you to find any electromechanical relay with a guarantee that its
must-close voltage is half of its nominal energization voltage.

---
You keep saying that ratio is "normal", but when a manufacturer
specifies the "must make" voltage as 80% of the relay's rated voltage,
then the voltage across the coil must never be allowed to fall below
that when the relay is being energized.

If it's allowed to fall below that point, then even though the relay
may make, its ON delay and bounce specs will no longer be valid, with
the increased bounce time certainly being detrimental to the relay's
lifetime.

But that 50% margin is bogus since any manufacturer's guaranteed "must

No, I merely added a capacitor across the output of _your_ proposed
full wave rectified 120 VRMS 60Hz source (170V peak) in order to get
smoothed DC closer to the relay's must-make current.

Hmmm.... 5 newsgroups.... where's my soap box?

Usenet, blogs, forums, and mailing lists are much like a trash
dumpster. At the bottom of every dumpster is a gem. All one needs to
do is dig through mountains of garbage in order to find it[1]. I try
to include some of those gems in my postings, no matter how far off
topic. As a general rule, one should not write anything that one
would not personally want to read.

In this case, there are some common indications of articles not worth
reading. My list includes:
1. One line replies. These are usually devoid of any thought,
substantiation, or useful detail.
2. Massive crossposting. This suggests that the OP hasn't bothered
to research the topic before asking, usually resulting in a question
with insufficient detail necessary for a productive answer.
3. Large numbers in the line count. This suggests that the author
has included massive quotes from the previous discussion, usually
automatically reformatted into an unreadable mess. Best to skip to
the next message in the thread, which usually includes the one line
the author has added.
4. URL only. Invariably, it's spam or self promotion.
5. All CAPS in the Subject line. That's usually spam, but sometimes
is from someone that can't type. Occasionally, it's used for its
original purpose as shouting. Unless you're into emotional content,
it's not worth reading.
6. Change of Subject line. The author doing that, instead of
starting a new topic, is usually a Usenet lawyer, more interested in
form than content. In most cases, the change of topic doesn't do much
as few readers bother to read the header. Some readers will
optionally start a new thread when the subject line changes. These
are probably worth reading, but with some suspicion as to the
motivations of the author.
7. Unsubstantiated offers of truth. These are declarations of fact
or truth based solely on the reputation or authority of the author. My
assumption is that the author usually can't prove his point if pressed
and therefore supplies no substantiation. This is difficult because
many well known authorities on a topic are too busy to lecture on
Usenet and will often assume the reader will automatically accept
their point of view based on their reputation. Personally, I don't
care what someone things. I want to know why.

[1] The few times I've asked a question on Usenet, only a small
percentage of the replies were genuinely useful. When I asked a
really complex question, with considerable detail and background,
there were no replies.

We know that. I also know from observation of various mfr specs that
ac relays are normally happy on half the voltage at dc. The relays
I've seen the dual ratings on havent been significantly different to
others.

One seldom need worry about the must open rating. The must close and

I'm saying it already taken into account in teh design of the relay,
its an ac relay. All we need do is give it enough current, but not too

I'm talking about what relays actually do in the real world. Reality

I have to say that is false. Its fairly normal engineering practice to
use parts outside of mfr's specs so long as their effectiveness in
such conditions is verified, they can reasonably be counted on to
continue to operate satisfactorily, and so long as the level of
reliability that gives is sufficient for the app. And in this case the
OP has good motivation to do so.

On delay specs are seldom critical. If they are then of course you'll
hit the coil with full rated v - or as I used to do at times, much
higher for a small fraction of a second to get it switching faster.

Bounce specs, again whether its ok depends on the app, and effect on
lifetime depends on whats being switched, and what lifetime is in fact
required of the part.

Its not bogus at all. If you really want to settle this, take a pile
of random relays and test what v they actually do close at. Then we
can discuss why what you find and what the mfr says are different.

You're stuck on mfr spec when the situation is that the OP is strongly
motivated to use the part outside of its mfr spec. Engineers do that.

Your proposd BR+C delivers the right i for one specific relay. For

Then show me your circuit.

Just in case you've forgotten, your suggestion was to use a 240V AC
relay using diodes and 120V mains.

OK. :-)

First, in order to measure the coil's unexcited inductance, I set up
the experiment like this:

+---------+ R1 +-----+
| SINE OUT|--[30K]---+----|VERT |
| | | | |
| | [0.1µF] | |
| | | | |
| | [DUT] | |
| | | | |
| GND|----------+----|GND |
+---------+ +-----+
FUNCTION SCOPE
GRNERATOR

I then cranked up the generator's output to get a decent display on
the scope and changed frequency until I got a suckout on the scope.

That was at 110Hz so, since in a resonant circuit the reactances
cancel, the suckout was caused by the voltage divider formed by R1 and
the resistance of the coil.

The reactance of the cap at that frequency was:

1 1
Xc = --------- = ---------------------- = 14476 ohms ~ 14.5kohms
2pi f C 6.28 * 110Hz * 1e-7F

Then, since the reactances of the capacitance and the inductance are
equal (but of opposite sign) at resonance, we can find the inductance
with:

Xl 14500R
L = ------- = -------------- = 21 henrys
2pi f 6.28 * 110Hz

Next, I measured the coil's DC resistance, found it to be 4900
ohms,and in order to measure the coil's excited inductance, set up an
experiment, like this, in order to measure the coil current at 240V
60Hz:

0->120V
/
VARIAC / 0->480V 240V
+------+ / / /
120AC>--| HOT|--+ +--[AC AMPS]--+-------+
| | | | | |
| | P||S | |
| | R||E [DUT] [AC VOLTS]
| | I||C | |
| | | | | |
120AC>--|-NEUT-|--+ +-------------+-------+
+------+ BFT

I got 15mA with 240V across the coil.

Now, to find the impedance of the coil we can say:

E 240V
Z = --- = -------- = 16000 ohms.
I 0.015A

Then the inductive reactance of the coil will be:

Xl = sqrt(Z² - R²) = sqrt(2.56e8 - 2.4e7) ~ 15200 ohms

and, finally, the inductance:

Xl
L = ------- = 40.3 henrys
2pi f

TADA! ;)

Who can be bothered to read all that? You need to get your question
consice, you need to independently verify any answer you get. This is
not the place to learn anything except maybe to do your research
somewhere else.

Really?

Here are your previous posts to this thread:

Your first:

"Finally someone comes up with the correct answer."

Your second:

"Oh they don't do practical here! It's rare for them to get it right
either, this thread is no exception. Some of them even advertise their
place of work! I wonder how much business that has cost them."

Your third:

"That must be the explaination as to why so much crap has been written
on this thread!!"

Which of those gives the correct answer to the OP?
---

>I actually read the question.

More's the pity then, since you obviously didn't understand it.
---

>Of course your free to ramble on about relays instead of contactors if you like.

---
If you have any capacity for learning, you need to smart up on
reasoning and punctuation before you start talking about shit you know
nothing about.

Just to help you along, here's a clue:

All contactors are relays, but not all relays are contactors.

NO NO NO!
DC excitation of an AC-rated coil is never a good idea.
DC coils and DC-activated relays are designed very differently
from their AC cousins.
