YardMaster Power IN
The YardMaster Power input (Pins 5 and 6) supplies
power to the YardMaster controller, power for the Lamps,
and power for the TURNOUT outputs.
The YardMaster can operate at voltages between 6 volts and 20 volts, AC or DC, but if
firing turnouts then the power must be greater than 10 volts.
Typically the Accessories output of the power supply is used to power the YardMaster,
however track power can be also used. For example, the YardMaster can be run by
tapping off any track connection for block control operations where turnouts do not need to
be controlled.
T
he YardMaster can also use the same DC StationMaster input power.
When attached to a StationMaster the StationMaster AND YardMaster MUST
share the same transformer. If separate power supplies are used the YardMaster
WILL be damaged. As noted above the YardMaster and StationMaster can use
the same input DC voltage.
VERY IMPORTANT!!
