No DCC or LocoNet accessory product should be connected to the same transformer winding that goes to a booster (e.g. DB150 or DCS100).
DAC10, DAC20 and DS54 accessory decoders can share a common power feed provided that the power feed is wired the same way to each board i.e. all the board grounds end up connected together. The power feed to these devices should not go to any other DCC or LocoNet interface unit.
DTM16 (revision B onwards), DTM30, SIGM10 and SIGM20 boards can share power feeds: they have the same power supply design.
It may be possible to share a power feed between these boards and other units. However this cannot be guaranteed to be possible and a separate power feed would be preferred.
