2-channel bell/whistle trigger

Saw this on eBay. Would this be suitable to trigger the bell/whistle ion a sound card, instead of using reed switches. The repetitive nature of track magnets does wear thin. Would require at least 6-8 volts minimum to latch the relays.

Nice find. I would think these little modules would come in handy for all sorts of stuff.

I used to make a board called the “Smart Sound Trigger”. It would randomize the track triggered bell and whistle events. Kind of a pain to have yet another board in your loco, so those functions have now been incorporated into my Enhanced RailBoss control.

Tim, you had better buy one and let us know how it works, although I could see an issue if you have to toggle the switch as in “push on” then “push off”, a H0 Lenz DCC system I operate on has this feature and it makes it real arkward to do long-short-long for level crossings, unless you can program the sound card to do a L-S-L once it is triggered
I could see a use to remote control any remote switch’s (points in ozz talk) without a lot of wiring running thru the garden, just a power feed that all points (sorry, switch’s) could run off. I wonder what power they can handle, you may have to use a relay as well to switch any high current. Could you control 2 points?
Keep us posted.

Wayne,
my only ‘issue’ is the input voltage. If a constant 12 volt minimum required to close the relay contacts, then its use is limited in my opinion, as I typically like to run my trains very slowly. If input around 6-8 volts then I see a need for the board. 12 volts would definately close the contacts and around 6 volts may result in contact chattering and less reliable sound triggering. The ‘on’/‘off’ operation is not a problem for me.
