'[EE]: Packaged Solid State Relay'
2001\02\21@110443 by Shawn Yates

Hello,

       Is there any company out there that has taken a standard solid state
relay and put it in a nice box?  I am looking for something that is a box
with a cord that plugs into 110 commint out one side and a 110 receptical on
the other and two low voltage wires or screw terminals to hook a control
loop to.  The goal is to find something that is already UL listed so I don't
have to do anything but control it.

Thanks,

Shawn

Maybe you could try the supermarket for one of those
"24 hour programmable timers" that can switch your
appliances on/off. Then just hack into it to control
its relay??

As soon as you hack it, the UL/CSA rating is voided.

Thats what I thought of also.  But the same thing about voiding the rating
came up.

Probably not solid-state, but IIRC, there are some low-voltage systems for
home electrical use. They would have approved components.

ISTR a clever design using a merged transformer/relay so you short two
(galvanically isolated) wires to make the relay pull in, which could be
done with a MOSFET and a bridge rectifier or a low-voltage MOSFET SSR.

Since we're throwing out kludges, why not get a light sensitive switched
outlet --the kind that turn on/off porch lights at dawn/dusk; and control a
light bulb in close proximity all enclosed in a box?!?!

       There's a little "intelligent power module" that came with my "Power
On/Off" computer rebooter. It looks like a wall wart power supply (plugs
into the wall), has an outlet on it and an RJ45 or similar connector. You
put DC between a couple pins on the RJ45 and it sends power to the
outlet. You can probably buy just this box. I'll see if I can find the
manufacturer of it.

part 1 3930 bytes content-type:text/plain; charset=us-asciiFor that matter... Sears has a module for turning on a vacuum or a light when
you turn on a power saw.  Basically plug the saw into the sensing port, and
whatever else you want to come on in the other port.  Turn the saw on and the
other thingy comes on... may not be a solid state relay (not sure if this is
really important).

Hehehehe, this last post got me to thinking about those power saving modules
for monitors.
Check this out:
www.computergate.com/cgi-bin/prodinfo?sn=140718045123420&cd=AS02
The price is even right.
Just pulse something down the com line occasionally if you want it on.
Of course the off state latency might be troublesome....

Close.  Good price, but you are right, the 10 minute delay is kind of high.

My God!  What can you package and sell for $1.99 ?!?  I'll have to buy a
couple of these, just to see what I can do with them... Figure it has a
PIC inside?

Probably more like a CD4060 with RC oscillator. Reset chip with each burst from
the com port would do it. Then all you need is an opto coupled triac. Get power
for the 4060 from the com port.

My guess:

A 555 timer, a couple of diodes and resistors, an opto and a triac.

       Pricy ($60), but dead on for what I need.  You apply 5 volts and it
turns on.  Nice package, UL approved.  I like it.

It is not amazing, it is imported. Anyone can see that the price of
shelving the thing is higher than that. I have a feeling that this kind of
price is not right for certain classes of products, and should not be
accepted blindly. What if someone copies your next $50 product and sells
it for $5 in bulk after manufacturing it using labor that cannot go on
strike without being shot ?

Nah, I think it's something they need to get rid of stock on before they
can't sell them at all...  It's not like a modern monitor/PC setup needs
anything like this...  I'm sure that you wouldn't want to plan to use this
in anything high volume.  It'd be good for something that you only needed to
sell a few, and could afford to inventory parts --but only if it would work
for your app, which it seems it doesn't quite fit in this case...

Well, Dal has probably hit it closest of all.

I did buy two of them today. Came in much bigger boxes than I thought.
Small plastic case, maybe 3"x4"x1.5", pigtail EIA power cords (that's
poor, for the original hack idea}, DIN-5 (PC keyboard) jack, and a pigtail
mini-DIN-6 receptacle. 4 position DIP switch on the underside, to set time
delay; one setting is a 10-second "test" mode, that might make it almost
useable as-is, for some applications. LED in the top, presumably on when
the monitor is powered. Also in the package, a couple of complex adapter
cables, to handle PC or Mac keyboard or serial mouse, in various
combinations. More than $2 worth of parts, there alone.

After almost completely hacking through the bottom edge of the "welded"
box, I remembered the oldest trick in the book - hiding the screws under
the rubber feet - and the box opened easily. Definately not "an opto, a
555, a Triac, and a few caps and resistors"! This thing is complex enough
to be not worth hacking! Six ICs (LM339, 74HC221, 74LS00, 14029B, 14020B),
some 4 diodes, 13 caps, 21 resistors, an MOV, 2 fuses (one replaceable),
and a 120VAC/10Amp relay, with 5VDC coil!

Apears to take 5V from the keyboard circuit; not line-powered, only floats
in the hot side.

Has to be a dumper, as Dal said, no modern system needs it. They probably
have a warehouse full! Case lot is 20, according to the Web site. If you
could use it in its original configuration, it's a bargain. If you want to
strip it for parts, it's still cheap...
