Digitrax DB210-OPTO DCC Booster with Opto-Isolated LocoNet

The Digitrax DB210-OPTO is a high-performance DCC booster designed to add additional track power to LocoNet-based Digitrax layouts. It is especially well-suited for large home railroads and club environments where electrical isolation and reliability are critical.

The DB210-OPTO provides clean, stable booster power while keeping LocoNet communications electrically isolated — helping protect command stations and reduce the impact of wiring faults on complex layouts.

What the DB210-OPTO Does

The DB210-OPTO increases the amount of electrical current available to your track by acting as a dedicated booster. While your command station handles control logic, the DB210-OPTO supplies the additional power needed to run multiple locomotives, especially sound-equipped engines.

• Adds dedicated DCC booster power to your layout
• Designed for large layouts and multi-operator sessions
• Supports heavy locomotive and sound usage
• Integrates cleanly with LocoNet systems

Opto-Isolated LocoNet (Why It Matters)

The OPTO version of the DB210 features opto-isolated LocoNet connections. This electrical isolation helps prevent voltage spikes, ground loops, and wiring issues in one section of the layout from affecting the rest of the system.

This makes the DB210-OPTO a popular choice for:

• Club and modular layouts
• Large home railroads with multiple power districts
• Layouts with long cable runs or complex wiring

How the DB210-OPTO Fits into a Digitrax System

The DB210-OPTO works alongside a Digitrax command station such as the Evolution Express, Zephyr Express, or DCS240+. The command station sends DCC commands, while the DB210-OPTO provides additional track power to a dedicated power district.

Create Reliable Power Districts

On larger layouts, boosters like the DB210-OPTO are commonly used to create separate power districts. This helps isolate short circuits and keeps the rest of the railroad operating smoothly during sessions.

• Improves fault isolation
• Reduces system-wide shutdowns
• Standard practice on advanced layouts

Frequently Asked Questions

Is the DB210-OPTO a command station?

No. The DB210-OPTO is a DCC booster only. It requires a separate command station to provide DCC control signals.

Why choose the OPTO version?

The opto-isolated LocoNet design provides extra protection and reliability on large or shared layouts where electrical isolation is important.

Can I use more than one DB210-OPTO?

Yes. Multiple boosters can be used on the same layout to create independent power districts and support additional trains.

Does this work with wireless throttles?

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