Train-Tech SS4L Sensor Signals tusi lesona
Su'e le SS4L Sensor Signals, lelei atoatoa mo fa'ata'ita'iga o nofoaafi. O fa'ailoga nei, e fetaui ma fa'asologa o le DC ma le DCC, fa'aaoga masini infrared e iloa ai nofoaafi ma fa'aalia faailo talafeagai. Fa'atasi ai ma filifiliga fa'alilolilo tusi, fa'ailoga LED, ma fa'atonuga fa'apipi'i faigofie, fa'amautinoa le fa'atuatuaina o le fa'agaioiga mo au nofoaafi fa'ata'ita'i. Taulima ma le faaeteete ina ia aloese mai le faaleagaina tumau.
