Dispatcher Panel for "Concept" Layout

Not shown are the circuits which control all these LEDs.

I will have two separate modules that will interface with this panel.

Turnout Control Interface.

This interface provides signals from my MTH turnout solenoids. Each LED which shows turnout position is wired directly to each MTH solenoid (red position and green position). The interface module also includes a diode and series current limiting resistor for each LED. The LEDs are designated as E, N, S or Y.

Block Control Interface.

This interface provides a 12vdc signal which is provided via my MTH "AIU". I use the "ACC" terminals to select a track "block". This determines whether the track is "powered" or "not-powered". This same 12vdc signal is used to activate a "power" relay which connects the "TIU" output signal to the track. The block control interface also provides a current limiting resistor for each of the LEDs. These LEDs are all designated as "B".

See the diagram.
