Re: Wireless trip circuit for emergency stop

Wireless trip circuit for emergency stop

This wireless E-Stop system is used with a custom E-Stop and circuit breaker panel (shown). As a result I now have several ways to cut power to the track in an emergency. I can use either the separate E-stop buttons or the wireless controller. The wireless pendant controller merely disconnects a 12 volt power supply that is used as a holding voltage for the emergency stop circuit.

Note: The trip circuit simply removes track power from my Z4000. However power to my Z4000 transformer is also maintained (not shutdown) so that accessories powered by the Z4000 will also function as normal.

Since I use TIU Passive Mode and separate TIU AUX power the TIU is not affected by this E-Stop system.

Note: Alternate DC wireless control could also be used in place of the AC wireless control.

If I understand correctly you are remotely controlling 12V DC by removing the AC line power from a 12V DC wall-wart, HO train transformer set to 12V DC, or the like. Since you already have 12V DC available, here's another option; you have the remote fob on the left and a 12V DC receiver module with relay and screw-terminals.

Is there something special about the AC remote outlet you're using that makes it particularly suited to your Emergency Stop application? Big box stores sell similar remote outlets for holiday lighting for about $10.

The DC wireless remote switch shown would also work in this application. Exact item found on Ebay. Purchased this item for inclusion in my control system. Price was $4.29 US with free shipping.
