Standard Decoders

Standard decoders mean that you can control motor and one or more auxilliary/function outputs (for lighting, smoke etc.). These are NOT sound decoders. Choose based on size, motor power output, and required outputs.

Zimo standard decoders are probably the best available for fine motor control and offer a variety of CVs to assist in tuning outputs to get the best from your models.

Ask if you need help choosing! YouChoos holds stock of most of these decoders.

Function Decoders

Function decoders offer ONLY auxilliary/function outputs, and DO NOT have output for controlling motor or sound.

They have a wide variety of applications, but most commonly used to add lighting, smoke, or auto-coupling control to a vehicle that has no motor. For example, many modern steam locos have a DCC decoder socket in the tender, which gives control of the motor, so a separate function decoder can be added in the boiler of that loco to provide control of loco lamps, firebox glow and other special features.

Another common use is to provide DCC control of coach lighting, which is particularly effective where the decoder supports a stay-alive capacitor which helps eliminate flicker.

Accessory Decoders

Accessory decoders are static decoders on your layout, deployed to control points and lighting features. Some allow control of solenoid-style point motors, and others give fine servo-control for slow-action points. You need a DCC controller that understands how to drive accessory decoders (most controllers other than the very basic ones can do this).
