PLEASE NOTE: Due to chip shortages, MS decoders are temporarily supplied with alternative chips. As a result, ZIMO is temporarily applying a surcharge! We have partially incorporated this in the sales price.

MS500
Predecessor: None, new innovation
Miniature sound decoder with NEM-651 interface (6-pin pin connector) or with wires as type MS500, MS490R, MS490F. "MS-Sound" with fully digital 1 W sound amplifier. Connection for external energy storage via solder pads with a maximum capacity of approx. 1000 µF.
To allow for their small size, the decoders of the MS5000 family are NOT mfx compatible.

Connection diagrams can be found in the operating instructions Instructions for all MS decoders
