Universal Decoder Adapter PCB for 21mtc Decoders with resistors mounted according to customer specifications.
The board contains amplifiers for Aux3 and Aux4 (from logic level to approx. 250mA). The board therefor offers direct connection to 6 function outputs.
The size of 34.5 x 20mm allows to place this board directly into the plastic fitting used in many Marklin locos.
As an additional feature this bord offers pads for six SMD resistors, one for every function output. That way it's possible to connect LEDs directly to the board.
No need to have resistors solderd in the wire connections.
Connections on the upper side:
Front light (possibility to add resistor inline)
Rear light (possibility to add resistor inline)
Aux 3 (amplified)
Aux 4 (amplified)
Decoder plus (5x)
Track left / Loco chassis
Track right / Pickup shoe
Connections on the lower side:
Front light through resistor
Rear light through resistor
Aux 1 through resistor
Aux 2 through resistor
Aux 3 through resistor
Aux 4 through resistor
Aux 5 direct
Aux 6 direct
The board is delivered equipped with resistors for function outputs according to customer wishes.
Please specify desired resistor values for all outputs with your order. All E12 values are supported.
The three connections DC+, DC- and 5V can be used for a buffer circuit like the PowerPack
