MS990L
The loco board for
the large scale
decoder MS990L
(shown in smaller scale)
MS990 is produced and shipped in the fol-
lowing basic variations:
as
MS990L
with
3 x 14-pole pin connector
(see figure left),
the outmost pins on the left and the right pin con-
nectors were mainly added for a 2 x 14 pin Märklin
interface; the connectors are otherwise used rarely
(due to the doubled pins or a second SUSI inter-
face).
as
MS990K
with
2 x 12 and 1 x 12 pole screw terminals
(as mentioned above, the outmost connections on
the left and on the right side are not needed).
Special editions
(Mixture of pin connectors and screw terminals, or
editions with less outputs)
can be produced on demand.
