TCS 1527 WOW121 Diesel Universal DCC WOW Sound Decoder 21-pin MTC Format

10 In Stock

One Year Goof Proof Warranty
All TCS decoders are covered by a one year goof proof warranty.

The WOW121 is a universal sound decoder for locomotives with DCC-ready 21-pin MTC connectors, and can also be used with any of TCS' motherboards. The WOW121 requires a motherboard to interface with the locomotive. The motherboard will determine the support for the number of lighting functions as well as the type supported (LED or 12V/1.5V bulbs). A WOW121 decoder will support up to 8 lighting functions.

Note: Function 5 and 6 are not programmable, and will only output constant bright lights. Take this into account when wiring multiple lighting functions.

For a complete list of available sounds, check out the "Sounds List" under the "Documents" tab.
