I'm looking for suggestions on a 24volt relay with contacts that can
handle 120V, 7 amps. I'm looking to install it to control a new 120V
outlet that is going in an attic and needs to be controlled by a 24V
signal to turn it on. So, I'm looking for one that is cost effective
and can be mounted in some simple type of wiring box. If it can go in
the same box as the outlet, even better. I'd like to make this code
compliant and do it right. Plenty of space is available as I can
mount just about anything on a stud in the unfinished attic.

Thanks for any input.

After posting, I realized that while I said I only need 7 amps, since
it's an outlet on a 15 amp circuit I guess I actually need one capable
of min of 15 amps.

I would use a RIB "relay in a box". Most electrical, HVAC and
electronics supply houses have them in stock.

What are you attempting to automatically control with the relay ?

What is the source of the input control signal ?

The most difficult issue for you is going to be finding an enclosure
which isolates the line voltage side of the relay from the low
voltage...

Depending on what you are using for your control input you might
want to find a relay that is made by the same company as the
rest of the equipment in place... It would also be a good idea
to obtain information from the OEM asking them if using the
equipment with an external relay is safe and won't interfere with
the normal operation just so that whatever accessory you are
going to be controlling via the relay won't void a warranty or
something like that if external relay terminals aren't provided...

I was going to suggest a typical boiler relay like Taco SR501, but then I
saw both John Grabowski's, and gfretwell's replies, which make even more
sense. I don't know the one John suggested, but if you can live with the
amperage rating, it's a nice self contained unit. The rr7 that gfretwell
suggested, does need a 24 volt power supply, but it has a high amperage
rating, and those relays will last forever.

It is a sweet little relay. It's kind of like the electric heat relays only
smaller. I've been buying from Tequipment recently, in fact I just got a
couple of proximity voltage testers today, and I got my last pair of Klein
lineman's from them. They have incredibly low prices, and being in NJ the

said it would ship out the same day I called and I would have it the next
day. Sure enough I received it the next day. I will check out their prices
for tools.

Are they "Tequipment.net"?. I could always use a source of low priced
Klein tools.

Of the suggestions, it looks like the one that will work is Daring
Dufas's relay in a box suggestion.

http://www.functionaldevices.com/pdf/RIBU1CW.pdf

It meets all my requirements:

easy to mount as it comes in it's own box
15 amps so controlling outlet on 15 amp circuit is OK
takes 24V input
available online for $21

One remaining question. Someone mentioned isolation of the 24V
circuit from 120V circuit? I would assume that since an electrical
equipment manufacturer is making these relays and they are UL listed
they are OK and meet code for my application even though the 24V wires
obviously go into the same box as the 120V wires?

Thanks again for the suggestions

Happens inside your heating systems so I'm guessing it's ok. If you
want to go cheap look behind some hvac contractors on the weekend for
junk ac compressors. They all have a relay that is pulled with 24vac
and handles anywhere form 20 amps and up. The hvac guys call them
contactors but it's just a relay.

HVAC guys use 24 vac relays often enough. Should be easy
enough to get one.

HVAC guys and control system guys like me use the RIB because
we're lazy and don't want to have to do a lot of screwing around
to accomplish a simple task. I'll pay $20 for a manufactured
solution rather than blow $100 worth of labor to build my own.
It's simple economics, I only build things that aren't available
off the shelf for a reasonable price.

They can both be in the same box when required - such as to connect to a
relay. Just keep the wires separate.

If there is not separation between line and low voltage compartments within
the enclosure, I would recommend connecting line voltage conductors to the
low voltage terminals, then run them outside the enclosure through a
knockout, where you can splice them to typical low voltage conductors.

When you have "low voltage" conductors in the same box as line voltage
the whole low voltage circuit needs to be treated as "class 1" which
means it needs to be treated the same as you would treat the line
voltage. Everything needs to be in a box, conduit or in a cable like
Romex, end to end.
When you have separation you can treat the low voltage side as "class
2" and you can take the liberties we usually have with "low voltage".
It is really a little more complicated than that but you see what the
general implications are.- Hide quoted text -

I think I may see an out here. Upon closer inspection of the
datasheet, the "relay in a box" that I want to use has what appears to
be a plastic divider inside the box that seperates the low voltage
section from the line voltage. Essentially it's like two seperate
sections. Does this make it OK to use as I intended?

Here's a pic and the datasheet:

http://www.functionaldevices.com/pdf/RIBU1CW.pdf

I also looked at their app notes and they sure show a lot of
applications where similar relays are being used in end user type
installations as opposed to OEM.

I wonder how it is that hvac components don't cause this issue.
Inside air handlers and outside units there is both 24vac and
110/220vac circuits. There is no specific separation of the wiring
inside the units. Low an dhigh get co-mingled all over the place
inside the units. And the 24vac wires go between units and the
thermostat without any special treatment. Does the brown jacket on
the low voltage wires count as satisfying the "class1" requirement?
Is all that is required a 2nd insulation layer like house wiring?
Because it would be easy enough to use thermostat wire for the low
side of whatever it is he is doing.

Thanks for any input.
I was going to suggest a typical boiler relay like Taco SR501, but then
I
saw both John Grabowski's, and gfretwell's replies, which make even more
sense. I don't know the one John suggested, but if you can live with the
amperage rating, it's a nice self contained unit. The rr7 that gfretwell
suggested, does need a 24 volt power supply, but it has a high amperage
rating, and those relays will last forever.
*Roy I recently discovered these when a customer asked me to fix his
closet
light. I thought that it was a nice compact unit that is made to fit in an
electrical box. It can also be used to replace relay switches. The OP
didn't mention what the load consisted of so I threw it out there for him
to
decide if he could use it or not.- Hide quoted text -

Of the suggestions, it looks like the one that will work is Daring
Dufas's relay in a box suggestion.

http://www.functionaldevices.com/pdf/RIBU1CW.pdf

It meets all my requirements:

easy to mount as it comes in it's own box
15 amps so controlling outlet on 15 amp circuit is OK
takes 24V input
available online for $21

One remaining question. Someone mentioned isolation of the 24V
circuit from 120V circuit? I would assume that since an electrical
equipment manufacturer is making these relays and they are UL listed
they are OK and meet code for my application even though the 24V wires
obviously go into the same box as the 120V wires?

Thanks again for the suggestions

If there is not separation between line and low voltage compartments within
the enclosure, I would recommend connecting line voltage conductors to the
low voltage terminals, then run them outside the enclosure through a
knockout, where you can splice them to typical low voltage conductors.


When you have "low voltage" conductors in the same box as line voltage
the whole low voltage circuit needs to be treated as "class 1" which
means it needs to be treated the same as you would treat the line
voltage. Everything needs to be in a box, conduit or in a cable like
Romex, end to end.
When you have separation you can treat the low voltage side as "class
2" and you can take the liberties we usually have with "low voltage".
It is really a little more complicated than that but you see what the
general implications are.

"725.136-D Associated systems within enclosures
Class 2 and 3 circuit conductors in ...boxes... shall be permitted to be
installed with electric light, power... circuits where they are
introduced solely to connect the equipment connected to Class 2 and
Class 3 circuits, and where (1) OR (2) applies:
(1) The electric light, power... circuit conductors are routed to
maintain a minimum of 0.25 in. separation from the conductors and cables
of Class 2 and Class 3 circuits."

The separation required is 1/4" between conductors. The class 2
conductors can attach to the relay in Dufas's relay box as long as they
are kept 1/4" from power wires

Using a barrier is another method (725.136-B).

----------------
There should not be a problem with using a listed relay/contactor in a
listed box (where the combination is not listed together).

----------------
The relays that gfretwell and John showed take minimal space in normal
boxes, which makes them easy to use in normal wiring (in addition to
having the low voltage wires outside the box). It is an advantage if
they are installed where exposed (like a basement) to replace the relay
in the future. Both are available as 2 wire or latched (momentary) versions.

I'm looking for suggestions on a 24volt relay with contacts that can
handle 120V, 7 amps. I'm looking to install it to control a new 120V
outlet that is going in an attic and needs to be controlled by a 24V
signal to turn it on. So, I'm looking for one that is cost effective
and can be mounted in some simple type of wiring box. If it can go in
the same box as the outlet, even better. I'd like to make this code
compliant and do it right. Plenty of space is available as I can
mount just about anything on a stud in the unfinished attic.

Thanks for any input.

DigiKey.com They will have what you need. ww

Radio Shack, and similar, have remote switches for electrical outlets. Meant
to control things like lamps from across the room by radio control, they may
very well fit your needs. They're very cheap, like under ten dollars.

MR-101 or PAM-1 should do what you need, also I think Air Products
sells a similar one that mounts to a knockout of a handy box which
might be exactly what you're looking for. Don't remember part number
off the top of my head.

You probably won't be able to mount it in the same box as the outlet
for box fill reasons. I'd put it up in the attic so you don't have a
blank plate showing in your living space.

Check out X10.com. They have what you need, it's wireless, and requires
nothing special but an outlet. You could have as many switches to control it
as you wanted. Right now it's $19.99 but prices change often there.
I've nothing to gain from them; just love their toys & products.

Thanks for the suggestion, but I can't use X10 for two reasons. One
is the control signal comes from a controller that already supplies a
24volt output. That also rules out some of the suggestions where the
transformer function is already included in the relay. The second
problem with X10 is reliability is a concern.

I still think Daring Dufas's relay in a box fits all the reqts.

24VAC or 24VDC?

For 24VAC what you want is a pump start relay that works with 24VAC
sprinkler systems. Already complete in a box. Start he
"http://www.google.com/products?q=pump+relay+irrigation&hl=en&aq=f".

For a 24VDC coil, 10A contacts relay go to
"http://www.allelectronics.com/make-a-store/item/RLY-2024/24-VDC-DPDT-10-AMP-RELAY//1.html".
You'll have to put it into an enclosure yourself.

Try something like this

http://dale-electric.com/search.php?...facturer=&keyw....

The RR7 is a good choice
It has a turn on and a turn off coil and latches in the last state you
put it in. You control this with a momentary contact SPDT center off
sw.

I controlled a relay like this powering the coil with only 9v
batteries. Since there is no hold-in current required you can put a
capacitor in parallel with 3 9volt batteries and use a couple of push
buttons to control it. The batteries will last practically their shelf
life.
