Hi

Not sure if anyone uses this type of 'Micron' Tx72v2 transmitter ?
But I am after a way to switch about 8 relays via the unit.

I don't mind if it's split/spread over 2 or 3 channels,
as it has 12 & I won't need this many.


Now it works on a 'Spectrum' base,
& wasn't sure if I could use something like an 'Orange' 9-way receiver,
to get at least 5 switches ?

At worst I could use latching relays,
if I can only get a pulse from the transmitter.


Was just trying to get the cost down,
as the R60 receivers are not cheap in the UK.

Or any other suggestions.


Thanks.

Hi Chris, 

No that doesn't work.


A standard RC receiver, only provides servo signals,
that can control servos and speed controller.

To perform voltage on/off switching,
you would need additional switching devices,
that translate the servo signal into voltage on/off.


Furthermore you may not mix up the basic meaning of "channels" in the RC world,
and the 12 "positions" of your control knob for switching on your Micron transmitter.

This knob only uses 1 channel,
and simply divides the transmitter signal for 1 channel, into 12 signal-segments.

Hi

It turns out it can be done, using the RX60 receivers & fitting FET buffers,
to convert outputs for low power switching, or switching a relay coil.

Will have to buy the more expensive RX60 receivers.  


Thanks

I have used FETs which allow P outputs to switch high current devices such as coils & motors.

Many thanks Rod.

This helps a lot with a drawing.  And only £00.50 each.
Like this.


Have ordered from :
Would I be able to use this on terminal 5 as well, on the R60 ?
Or just 3 & 4 ??

You can use this FET on any P output. 

If you use RX65 & 66 they are made with three F outputs,
which won't require the MOSFET.

There are maybe smaller SMD MOSFETs with the characteristics of the IRF3706,
but electronic experts will have to tell us what that is.

Hi


I was only able to get the RX60,

as there seems to be a wait on ones above this at the moment,

& that date keeps getting moved forward.


Thanks for the help.  :2t:

Just as another note.

I see you can buy a '16 R.F. Relay Switch',
that can be programmed to, 16 latch, 16 pulse, or 8 latch & 8 pulse,
in 12 or 24 Volts.

Very handy for $18 / £13

Can you share a link to where to buy, please?

There is a simple 'function-button' Icon in the Freerails 'Main Reply Window'.

It is there to deal with Posting Links effectively & appropriately labeling them.


It is the 'World Globe With Chain Link' in front of it Icon, top row, third from right.

Using it, allows you to Paste your Link, into the 1st 'popup-box' that appears.


After Pasting your Link into that box & clicking OK, the 2nd 'popup-box' appears.

This allows you to appropriately name, the Link you've just Pasted in, as you wish.


After that, clicking OK again, takes you back to the Freerails 'Main Reply Window'.


The Link, you've now appropriately named as you wish, using the 2nd 'popup-box',

appears where the cursor was, when clicking the 'World Globe With Chain Link' Icon.


:cool:


Eddie
