Mains relay box with dry contact input

[Pete]

I'm looking for small quantities (usually less than ten a year) of a
pre-built and type-approved box of tricks that will take a dry contact
input and switch on or off a standard 240v mains output socket.

Does anyone know of anything that might suit?

Thanks, Peter

how many amps @ 240v ?
what is it driving ?
What rate of speed does it have to turn on/off at ?

What sort of input contact did you have in mind, can it sit at 240v
potential or must it be isolated from the mains ?

** Err - " dry contact = what ?

2A would be plenty.

what is it driving ?

Usually one 240VAC bell, sometimes two, 80VA or so each. Sometimes, it
may be used to switch other devices, like a 240VAC light.

What rate of speed does it have to turn on/off at ?

Usually 2 or 3 seconds on, up to 32 times a day, at least one minute
between on periods. Sometimes, as short as 0.25 seconds on, sometimes
as long as 8 seconds on.

What sort of input contact did you have in mind, can it sit at 240v

A low voltage relay contact will be used to drive it, and the switching
input *must* be isolated from the mains.

Does this help? If you know of something that won't quite meet the
specs, please suggest it anyway.

Thanks, Peter

Thanks, Phil. I do realise that the term "dry contact" is not
technically correct, but it's often used for the type of device I'm
looking for, as well as in many other industries. I am aware that the
"official" meaning of the term is that no voltage is applied to the
switch while it is actually switching.

So, let's just assume that what I meant was that I need to switch this
device on and off with a normally open relay contact. I am not able to
provide voltage to the switching device.

Doesn't sound like you'd want to build a kit, but DSE was selling
something like this. There might still be a few around in stores.

Hi, Phil. Thanks for your input. I'm not sure what else you'd need to
know other than the technical details I've already supplied. But, if
you need more before you can help, I'm willing to give it a try.

Basically, I have a device that is effectively a clock. It contains a
low voltage relay that gets turned on based on a pre-defined schedule,
up to 32 times a day. Usually, it turns on a 24VAC bell (or something
similar) at the scheduled times. The relay contacts and wiring are fine
for that purpose.

However, sometimes the end users want to ring a 240VAC bell that they
already have. The relay contacts and wiring are not suitable for
240VAC, so we want to use a type-approved external "box of tricks" that
has a 240VAC socket on it, and turn that on with our relay.

The small quantities make it uneconomic and impractical for us to
design, build, and get approvals for, such a box ourselves, *if* there
is something available that we can buy off the shelf at a reasonable
price. If we have to, though, we will, and the customers will have to
pay for it. Finding out whether there is such an existing device is the
reason for my question.

Does that answer your "will not describe their BLOODY app" objection?

To Bob Parker: I know about the DSE remote relay kit, but it's not
type-approved, so it's not really suitable. By the way, I have one of
your MKII ESR meters - thanks!

Here it is again !!

FUCKING ANSWER IT !!!!!!


By adding a $5 fucking plug pack - you can then use a HOST of readily
available solutions.

FUCKING ANSWER IT !!!!!!

By "box of tricks", I assume you mean my original device. No, there is
no AC power available. DC power is fed to the device via its data
communications cable. All that's available is as I've stated - a set of
n/o relay contacts.

However, there will obviously be a mains power point somewhere between
this device and the switching device that I'm looking for, since the
whole point is to switch 240VAC to a bell that may or may not be
physically close to my original device.

By adding a $5 fucking plug pack - you can then use a HOST of readily
available solutions.

Pointers to this "HOST of readily available solutions" would be welcome.
I'm not sure how a "$5 fucking plug pack" changes much, but I'm
willing to find out.

Remember, I'm looking for something that is type-approved - I realise
that a $5 plug pack and a mains-rated relay would *easily* do the job,
but that's not a neat and tidy solution and it's not energy authority
approved, and the end users would likely electrocute themselves hooking
it up.

** HOW UTTERLY ASININE !!!!!!!!!

From you initial post ;

" .. pre-built and type-approved box of tricks .. "

However, there will obviously be a mains power point somewhere between
this device and the switching device that I'm looking for,

** The device you asked for is to be fully approved fro 240 volt mains
se - right ?

THEREFORE it will have approved AC power connectors fitted (IEC or 3 pin
GPOs. )

SO **YOU** CAN USE A PLUG PACK TO SUPPLY a little DC to the
control input same device

FOOL !!!!!!!!!!!!!!!!!!!!

Off the top of my head:

Bunnings have a range of remote controlled mains switches, designed to
switch mains devices on and off via an RF remote. You could wire your
relay contacts across the switch on the remote control. These things
seem to be all the rage, plenty of different devices on the market.

Another solution which is clunky but may be suitable is to get a UPS
device with external on/off control.

I thought the kit being a kit and not type approved would probably
exclude it from consideration.
As Dave said, there are lots of cheap RF-linked mains switches
around which should be type-approved.
Thanks for getting one of the ESR meters!

The cheap radio link is no way accident safe, interference proof or other

This may well count it out for the OP's app as well.

** Like with the Arlec (and Jaycar ) 120 volt auto-transformers - the
safety issues cannot be discovered by simply looking at the product itself.
Which is all an inspections lab is required to do.

Our law makers have to BAN certain items as being inherently unsafe to have
on sale to the public.

They could start with the current crop of CFLs.
