Part #1104 SG-2 Signal Control Kit
Switches power from the switch machine for block signal (lamps) use (4).
INSTALLATION INSTRUCTIONS
This kit includes four (4) diodes. These diodes will allow you
to control up to 4 block signal lamps (on your control panel
or trackside). The power for these signal lamps can be supplied
by the same 12v DC current running your SwitchMaster switch
machine, because the motor receives a constant current.
Use the following schematic to install the diodes. Note that
the diodes have a SOLID COLOR BAND on one end of the
diode. These bands must be opposite each other in order to turn
one lamp on and the other lamp off. Voltage will only travel in
one direction through a diode, so a positive voltage gets through
to light the bulb, where a negative voltage will not.
