Description
The ESU 51830 SwitchPilot V2.0 is a compact stationary accessory decoder that brings digital control to your turnouts, signals, and other layout accessories. A single unit drives four twin-coil (solenoid) accessories plus two independent servo outputs, and it speaks both DCC and Märklin Motorola, so it drops into nearly any digital command system regardless of scale.

- Controls four twin-coil (magnetic/solenoid) accessories — turnouts, semaphore and light signals, magnetic uncouplers, or lamps — via eight transistor outputs arranged in four pairs.
- Two additional servo outputs for slow, prototypical turnout movement or animated semaphore signals.
- Multi-protocol operation with both DCC and Märklin Motorola (MM) command stations.
- Up to 1A total output current; powered from the digital track signal or an external DC/AC supply for heavier loads.
- Flexible output modes (pulse, momentary, permanent, and flashing) set by CV on a programming track or on the main with POM.
- Short-circuit and overload protected outputs; expandable with the SwitchPilot Extension for frog (heart-piece) polarization.
- Scale: Multi Scale — works on N, HO, O, and larger digital layouts.

What can the SwitchPilot V2.0 control?
It digitally operates up to four twin-coil turnout machines or other magnetic accessories (signals, uncouplers, lamps), plus two servo-driven devices such as slow-motion turnouts or semaphore signals.
Will it work with my command system?
Yes — it supports both DCC and Märklin Motorola, so it works with virtually any digital command station. It is intended for digital layouts, not purely analog (DC) operation.
Do I need a separate power supply?
The decoder can draw power from the track signal, but for reliable switching of multiple or heavier accessories an external DC or AC supply is recommended.
Can I expand it later?
Yes. The optional SwitchPilot Extension module adds relay outputs for frog polarization and other switching tasks.
