The NCE 5240233 AR10 makes reverse loops, wyes, and turntables completely hands-off on a DCC layout. When a train crosses into (or out of) the reversing section, the AR10 detects the phase mismatch and swaps the section's polarity in a fraction of a second — faster than any decoder or locomotive can notice. Trains glide through reversing trackage without a flicker, a stutter, or a toggle switch in sight.With a 10 amp rating, the AR10 has headroom for any scale — from N scale up through large-scale layouts and multi-unit lash-ups with sound. Solid-state switching means there are no relays to wear out, and installation is a simple four-wire hookup.Compatibility Works with any NMRA-compliant DCC system (NCE, Digitrax, and others) Rated up to 10 amps — suitable for all scales including O and G Handles reverse loops, wyes, and turntable bridges How to Use Fully gap both rails at each end of the reversing section Connect track bus input to the AR10, and its output to the reversing section Run trains through — the AR10 corrects polarity automatically Specifications Type: Automatic reverse loop controller (solid-state) Current Rating: 10 amps Power Source: DCC track bus Brand: NCE Corporation Item Number: 5240233 (Walthers 524-233) About NCE: NCE Corporation (USA) is a leading manufacturer of NMRA-compliant DCC systems, boosters, circuit protection, and layout automation electronics.
