reverse loop module
Posted by mxgallan on Monday, February 05, 2018 4:57 PM

hi, ok i'm sure this has been discussed on here in length, so what reverse loop module best suits a nce dcc system. i know digitrax, mrc, lenz. psx and bachman all have them,  but which one is the best in compatability and reliability.

The "best" is probably the PSX-AR by DCC Specialties. Sold by Tony's Train Exchange and others for about $45.  Adjustable trip values for the circuit breaker, can automate the  in/out turnout.

The PSX-AR is a highly reliable auto-reverser. It is a solid state unit that reacts quickly to an electrical short. I have four of them on my layout.

The Digitrax AR-1 relies on a mechanical relay to correct an electrical short and, as such, it reacts a bit slower. Because of this, the AR-1 can be problematic if it is placed downstream from solid state units such as a PSX circuit breaker.

The AR-1 is a lot less expensive than the PSX-AR, so it all depends upon the rest of the electronic setup on your layout. At one time, I used AR-1s for my reversing sections, but when I decided to create power districts and protect them with circuit breakers, the AR-1s became less reliable, so I replaced them with PSX-AR units.

A member of my club has a reverse loop Y on his layout and uses the PSX-AR.  Works like a charm.  I am with Rich and Roger on this one.

I've got a couple of PS-REV units.  They're the older version of the PSX-AR.  After 10 years, they're still working flawlessly.

Tamvalley dual frog juicers works well, just installed a second reverse loop on my layout last night using a FJ flawless easy installation.  If you want make it automatic (switching the switch) go with DCC SP PSX-AR works very well. I use a Power Pro 5 amp system no problems with either one.

One more vote for the PSX-AR from Tony's. Solid state and reliable. I have two that are about 15 years old, and they are as good as ever. They were about $25 then; about $45 now. But there are a couple of models, some with additional features, I think. Mine do reversing and power management. If there's a short in the loop, the PSX-AR does not shut down the rest of the layout.

I also have a Digitrax AR-1. It is a mechanical relay sort of thing. It makes an audible 'click' when a train passes the insulated gap whether the polarity is reversed or not. But that is not necessarily a problem because every reversing section either starts or ends at a turnout, and there is the normal 'clickity-clack' as the train crosses the turnout frog anyway.

I have a NCE 5A Powerhouse Pro system and have 2 OG-AR auto-reversers that are 6 yrs and counting, no issues.  I knew I did not want one with a relay, so the discussion started there.  They are now $32 and I chose them basis conversation with a Tony's fellow, which I highly recommend for peace of mind regarding what will work well with your particular system and intended use (amps per power sub-district, etc.).  Note that it is NOT for use with the NCE Powercab nor Digitrax Zephyr, thus I encourage that talk with Tony's.  

The PSX-AR is showing at $54 now.  So if the extra $ are not a biggie, or your system might need the adjustability of the trip setting, etc., that might be your need (or preference).

Another consideration is features such as trip indicators and related connections.  I did not consider that in making my choice, early in the layout process.  My reversers / circuit breakers are under the table so I can not see any indicator lights.  In the OG-AR case, I was lucky that there are easy connection points for external LEDs to flash when the breaker trips (short circuit) so I added LEDs to my track diagram on my control panel, a nice feature as I can tell at a glance that a short has occurred in one of my 3 sub-districts.
