DCS and Conventional Wiring scheme:
On my concept layout I use shielded pairs of 18 gauge wires which are attached to each track block (connected in the middle of the block). This cable is the same used for security systems. My block lengths are no longer than 6 feet in length.
Each block is controlled by a separate relay. Each block has individual 3A circuit breaker protection. Block control is by using a toggle switch panel or my TIU/AIU using a 12vdc wiring scheme.
All turnouts use AUX power and are controlled by a relay. Turnouts can be operated using pushbuttons or my TIU/AIU. The turnout motors are protected by current limiting and separate fuses.
I use a circuit breaker on each TIU output. I also use a circuit breaker on each TIU input.
Track power is obtained by two MTH Z-4000 transformers. One Z-4000 is wired for conventional operation only. The second Z-4000 is wired for DCS operation only.
