Marklin 74462 - Installation Digital Decoder (C Track)
Marklin says this is the new version and identical to the 74461. This decoder can be installed in all C Track turnouts with an electric mechanism. The digital formats supported are mfx; Motorola; and DCC.
Connections are with plug contacts. An address from 1 to 256 can be set with coding switches.
A digital decoder can be installed simultaneously or later on, with the electric mechanism for turnouts (74491).
The decoder is simply connected with plug contacts and it can be given a custom address for each turnout (Address 1 to 256). Tools or special knowledge is not required for the installation. The digital current supply can be taken directly from the train operation contact for the turnout. This gives you a finished digital turnout that is immediately ready for use on temporary layouts.
