Not quite clear exactly what you're trying to do, but for about 1/2 the price and with beefier relays...

Currently running 2 loops using 2 channels but sometimes i just want to run one loop...i have been pulling one track feed at the TIU to disable the one loop...hmmm..just dug out my DCS manual to see if i can disable a channel via remote...never done it before.

You could  install an ON/off toggle between the power supply & tiu. You can disable a var channel in var mode.. just don't address the track. Whether a toggle or  wireless it's still one push of a button.

Seems the relays are only around 7 amps and they're going to take forever to ship from China?  

How do you easily disable fixed one or two with the remote? TIU is powered w/ a z500 aux in.

You can't.

Not to mince words but exactly what do you mean by "disable"?

Even an un-powered TIU makes an electrical connection from Fixed Input Red to the same Fixed Output Red.

When i remove either lead  from the output channel (ex. fixed 2) that loop becomes disabled. I would like to do this  wirelessly. Basically interrupting the output feed to the track.

Then "yes" to your initial question.  For example use the "A" relay and "A" FOB button to disable/enable Fixed 1.  And use the "B" relay and "B" FOB button to disable/enable Fixed 2.

Note that you can "teach" the relay receiver how to interpret the button presses - jog, interlock, toggle etc.  In other words press A to turn enable Fixed 1.  Press A again to disable Fixed 1.  Most of these relay receivers have an inter-lock mode which, for example, allows you to Press A to enable Fixed 1...but Press B to disable Fixed 1.  The instructions can be poorly worded though usually you can find a youtube video where someone has figured it out.

Also, think through how you want the relays to start up when you initially apply layout power.  So if most of the time you have both Fixed 1 and 2 enabled, you probably want to use the NC (Normally Closed) relay outputs so power flows through from TIU to track on both loops.  Then you disable one or the other loop by pressing the fob button. 

Also, note these are NOT latching relays.  So when 12V DC power (e.g., from a wall-wart) is removed from relay module all the relays will turn off.

Thank you stan/gregg...

This one says self lock....does that mean self latching?

edit: from reviews questions

When press on the remote ..is the relay will be on "momentary " or "latched "position..(on/off) relay.?

answer:There is a jumper that will allow you to set momentary or latched. There is also an "all relays at once" setting, but I have used that one.

Right.  From the Amazon page it specifically says,

2. Self-lock - pressing the button is working and pressing the button again is stop

As mentioned previously the more common definition of a latching relay is one that maintains its position even when power is removed.  However, in this case I'm 99% certain that if you remove power to the relay module, the relay will turn off.  And when you apply power again, the relay will still be off.  But as long as you give the module 12V DC power, it will behave as a latching relay; press button to turn relay on, press button again to turn it off.  Lather, rinse, repeat...

The chinese relay fog bank has been lifted...and thanks again
