Digitrax DB210 Auto-Reversing DCC Booster

The Digitrax DB210 is a high-output auto-reversing DCC booster designed to expand power capacity and simplify wiring on LocoNet-based Digitrax layouts. It can be used as a standard DCC booster to add power districts, or configured to automatically handle reverse sections such as loops, wyes, and turntables.

This dual-purpose capability makes the DB210 a popular choice for expanding home layouts and advanced operating setups that require both additional power and automatic polarity control.

What the DB210 Does

The DB210 works alongside a Digitrax command station, which provides DCC control signals. The booster supplies additional electrical current to the rails, allowing more locomotives — especially sound-equipped engines — to operate reliably.

• Adds dedicated DCC booster power to a layout
• Supports multiple locomotives operating simultaneously
• Ideal for sound-equipped engines and larger layouts
• Integrates seamlessly with Digitrax LocoNet systems

Built-In Auto-Reversing Capability

The Digitrax DB210 also functions as an auto-reversing booster. When configured for reversing operation, it automatically manages track polarity in reversing sections without requiring a separate auto-reverser module.

This is commonly used for:

• Reverse loops
• Wye track arrangements
• Turntables
• Balloon tracks

When a train enters or exits the reversing section, the DB210 automatically detects the polarity change and switches instantly — keeping operations smooth and uninterrupted.

Standard Booster or Reversing Booster — Your Choice

The DB210 can be configured as either:

• A standard DCC booster for a normal power district, or
• An auto-reversing booster for a dedicated reversing section

This flexibility reduces wiring complexity and eliminates the need for additional reversing hardware.

How the DB210 Fits into a Digitrax System

The DB210 requires a separate Digitrax command station to operate. Common pairings include Zephyr Express, Evolution Express (wired or wireless), and DCS240+ systems.

The command station provides control commands, while the DB210 supplies power to a specific power district or reversing section.

Home Layouts vs Club Layouts

The standard DB210 is ideal for most home layouts with straightforward wiring. For very large layouts, modular setups, or club environments where electrical isolation is important, Digitrax also offers an opto-isolated version.

Frequently Asked Questions

Is the DB210 a command station?

No. The DB210 is a DCC booster only. It does not generate DCC commands and must be used with a separate command station.

Do I need a separate auto-reverser?

No. The DB210 includes built-in auto-reversing capability, eliminating the need for a separate reversing module when powering reverse sections.

Can I use more than one DB210 on my layout?

Yes. Multiple boosters can be used on a single layout to create separate power districts and support additional trains.

Does the DB210 work with wireless throttles?

Yes. Booster operation is independent of throttle type. Wired and wireless throttles both benefit from increased track power.
