Power Distribution Hub
Latching WAGO Terminals: Battery Input and High-Current Channels For Battery Input use 18 to 4 AWG Wire, Stripped back ~0.75” (20mm) For High-Current Channels use 24 to 8 AWG Wire, Stripped back ~0.5” (12mm) Flip open the lever with an upward motion. You can open the lever all the way to have it stay open or you can open it half way for quick wire changes.
Turns on/off the mandatory 120Ω for CAN termination. This should only be on if the PDH is the last device in the CAN chain.

Power Distribution Hub
3. Current Monitoring: The PDH includes built-in current monitoring capabilities, which allows you to monitor the current draw of each connected device. This feature is valuable for diagnosing electrical issues, optimizing power usage, and ensuring that you don't exceed the capabilities of your power source.
4. Protection and Safety: The PDH incorporates safety features to protect your devices and the overall electrical system. These features may include built-in circuit breakers or fuses to prevent excessive current flow and protect against short circuits.
6. Expansion and Modularity: Some PDH models offer expansion capabilities, allowing you to connect multiple PDH units together for larger systems. This modularity makes it easier to scale your robotics project and manage power distribution across a wide range of devices.
1. Inputs: The PDH typically has multiple input ports, allowing you to connect various power sources, such as batteries or voltage regulators. It is often used as a central hub for power in a robotics system.
2. Power Outputs: The PDH has multiple output ports that are connected to the various devices in your robotics system, such as motors, servos, sensors, and other electronic components. These outputs provide regulated power to each connected device.
5. Wiring Organization: One of the primary benefits of the PDH is its ability to simplify wiring. Instead of running multiple individual power wires from your power source to each device, you can connect all the devices to the PDH, reducing clutter and improving the overall organization of your electrical system
Overall, the REV Robotics Power Distribution Hub serves as a central power management solution, simplifying the wiring process, providing regulated power to devices, and enhancing the safety and efficiency of your robotics or electrical system. It is a popular choice among teams and individuals participating in robotics competitions or building complex robotics projects.
Compatibility
As shown, not all motor controllers are the same. All FRC legal motor controllers are compatible with all FRC legal brushed motors. However at the time of this writing only one stand alone motor controller is FRC legal to be used on brushless motors.
