EX8874 Motor Shield โ High-Current DCC-EX Track Power & Control
The EX8874 is a motor shield / power board for DCC-EX command stations, designed for users who need more current capacity, stronger protection, and a more expandable build.
This is an upgrade/add-on for DCC-EX command stations.
The EX8874 Motor Shield provides higher current output and improved power handling, making it ideal for larger layouts, multiple locomotives, or more demanding installations.
Important: The CSB1 command station is not included. This product is the EX8874 motor shield only and is intended as an upgrade / add-on for compatible DCC-EX command station builds.
โ๏ธ Choose this if you need more power or are building a custom DCC-EX system
โ๏ธ Ideal for larger layouts or running multiple locomotives
โ Not required for most plug-and-play Ready-to-Run setups
The EX8874 is commonly chosen for larger N, OO, or HO layouts where additional current headroom and enhanced protection provide smoother, more reliable running.
Using a Ready-to-Run system? You may not need this upgrade. The EX8874 is best suited to custom builds using the CSB1 Core Unit.
- High-current track power: Designed to deliver up to 5A continuous output for larger layouts, multiple locomotives, and more demanding DCC-EX installations.
- Designed for DCC-EX: A dedicated motor shield / power board for DCC-EX command station builds.
- Protection built-in: Helps safeguard your system with overcurrent, short-circuit, thermal, and reverse-polarity protection.
- Main and programming track outputs: Suitable for command station builds needing reliable track power and programming functionality.
- Ideal for expansion: Useful when you want more dependable power handling, additional headroom, or a modular build that can scale with your layout.
