LS100 Accessory decoder for 4 turnouts with feedback
Accessory decoders are the link between your NMRA DCC system and your function devices (that is turnouts, signals, uncouplers, etc. on your model train layout.
Accessory decoders receive commands sent from the command station via the power station and activate the drives of turnouts or other switching devices. For DIGITAL plus systems these switching commands are activated from input devices, such as, hand held controller LH100, tower cab LW100, interface LI100 or translation module LC100 in connection with another, compatible digital system.
