Printed circuit board for decoder installation in Märklin BR17, the S10 (Kaiser Wilhelm Train) as well as BR 18.1 with long tender.
Ready assembled with 21mtc interface and resistors, ready for installation.

With this version the outputs Aux 3 and Aux 4 are NOT amplified. So use a decoder with amplified outputs Aux 3 and Aux 4 if you want to use them (at ESU the decoders with MKL in the designation).
If you want to use a decoder with unamplified outputs, use our item number 8051mtc.
