Description
DCC decoder to detect if tracks are occupied. Detection is performed by measuring voltage over a resistor / (high speed) diode.
Feedback is provided via the (Lenz) RS_Bus.
Relays can be used to swich track power on/off.
The design is intended for a train display cabinet / shadow station. There are three tracks per level; to ensure precise track distance of 46 mm the tracks fit nicely in the PCB openings.
The PCB has been assembled by JLCPCB. The total costs for 15 PCBs with all SMD components assembled is around 150 Euro (including tax and shipping). Costs do not include the Through-hole components, such as relays, jumpers and terminals.
