Outputs for smoke units
« on: July 02, 2026, 09:05:49 PM »
I will be doing my first Rail Pro install. This is in a USA trains GP40 using a LM-5S-G. Can anyone tell me if outputs 7 and 8 can be turned on and off? I know smoke units take a lot of juice and shorten runs using batteries. Most likely will very rarely if ever use smoke, but would like to configure anyway.

Thanks in advance
Tom

The question you need to ask, what is the current limit on those outputs?

And you need to decide how you want to run the USAT smoke unit.

Depending on the configuration you can pull an amp with them... I doubt the RP module has that ability.
Lots of tips and techniques on my site: www.elmassian.com contact me greg@elmassian.com

Hi Tom, to review, on the LM-5S-G these on/off outputs are for higher current up to 2 amps. Use outputs 7 & 8 for smoke units, lots of incandescent bulbs or tripping couplers. Will work with any LGB /PIKO Seuth units. For Aristo  Craft you must use the Aristo adapter board. Bachmann steam or diesel engines use the Bachmann PCB005 plug in adapter board.  For USA smoke units use the USA smoke units PCB. Unplug from the USA lighting board. Redirect the black wires to terminal 7 or 8 and red to +V screw terminal on the LM-5-S-G.
