Uhlenbrock Switch-Control 63400
Connection Module for Track Diagram Control Board
(Translated and revised by Modell-Zug Elektronix, Rev. 01/2006)
1. Description
The Switch-Control 63400 provides the interface between a Track Diagram Control Board (TDCB) and an
Uhlenbrock Digital system. It is suitable for use with all digital central units with a LocoNet connection
such as the Intellibox, TwinCenter, Daisy, etc. The Switch-Control 63400 has 10 inputs for connecting
buttons and 10 outputs for lamps or LEDs with series resistors. The buttons or lamps can be connected
individually or as part of a TDCB, such as those available from companies like Heki and S.E.S.
2. Connection
Using the supplied LocoNet cable, connect the Switch-Control to the LocoNet T or LocoNet B output of
the Intellibox or TwinCenter, or with the LocoNet port of the Daisy system.
LocoNet Connection
Next, connect the two"16V~" terminal clamps to a 12-16V transformer, for instance the L-O outputs of a
standard Märklin transformer. It is possible to connect additional Switch-Controls or other consumers (for
example, house or street lighting) on the layout to the transformer feeding the Switch-Control. However,
there must be NO electrical connection between this transformer and the track or central unit in any way.
For this reason, a transformer that supplies the Intellibox, TwinCenter or a Booster can NOT be used.
CAUTION: Failure to adhere to this rule can cause permanent damage to the Switch-Control's circuitry!
The momentary push-buttons of the TDCB are each connected with one pole on the Switch-Control
"Taster" (Key) inputs 1 to 10, and with the other pole to the connection marked "Masse"
(Common/Ground).
The lamps are each connected with one pole to the lamp outputs 1 to 10 and with the other pole to the
connection marked "+" on the Switch-Control. It is important that the rated voltage of the lamps used are in
agreement with the output voltage of the connected transformer. (If using the L-O outputs of a Märklin
transformer, the Switch-Control lamp voltage will be approximately 20V.) If you wish to use LED
indicators instead, a resistor of 1.5Kohm (minimum) ¼-Watt must be connected in series with each LED. It
is also necessary to pay attention to the polarity of the LED, the cathode "K" of the LED must allows be
connected to the lamp output of the Switch-Control.
