# REV ION Control System Overview ## Refined Control Expand upon your robot's capabilities with the REV ION Control System. This series of Hubs and Modules provide flexibility for the addition of new peripherals while delivering vital feedback back to the team. Seamlessly integrate a Hub into your CAN Bus alongside the [SPARK MAX](https://docs.revrobotics.com/brushless/spark-max/overview) or [SPARK Flex](https://docs.revrobotics.com/brushless/spark-flex/overview) Motor Controllers.

## Power Management ### Power Distribution Hub The REV Power Distribution Hub (PDH) is the latest evolution in power distribution for the *FIRST* Robotics Competition (FRC). With 20 high-current (40A max) channels, 3 low-current (15A max), and 1 switchable low-current channel, the PDH gives teams more flexibility for overall power delivery. The Power Distribution Hub features toolless latching WAGO terminals, an LED voltage display, and the ability to connect over CAN or USB-C to the REV Hardware Client for real-time telemetry, making it easier than ever to wire and debug your robot. ### Radio Power Module The REV Radio Power Module is designed to keep one of the most critical system components, the OpenMesh OM5P-AC WiFi radio, powered in the toughest moments of the competition. Traditional barrel jacks easily work themselves loose and often require hacks, like hot glue, to prevent intermittent power losses. The Radio Power Module eliminates the need for powering the radio through a traditional barrel power jack. Utilizing 18V Passive Power over Ethernet (PoE) with two socketed RJ45 connectors, the Radio Power Module passes signal between the radio and roboRIO while providing power directly to the radio. After connecting the radio and roboRIO, easily add power to the Radio Power Module by wiring it to the low-current channels on the Power Distribution Hub utilizing the color coded push button WAGO terminals. ### Mini Power Module The REV Mini Power Module (MPM) is a compact power distribution module that allows you to securely and quickly power peripheral devices to your robot. Need more low-current channels on your PDH? Wire the MPM to one of the high-current channels on the PDH to power more peripheral devices and custom circuits. ## Pneumatics

### Pneumatic Hub The REV Pneumatic Hub is a standalone module that is capable of switching both 12V and 24V pneumatic solenoid valves. The Pneumatic Hub features 16 solenoid channels which allow for up to 16 single-acting solenoids, 8 double-acting solenoids, or a combination of the two types. The user-selectable output voltage is fully regulated, allowing even 12V solenoids to stay active when the robot battery drops as low as 4.75V. Digital and analog pressure sensor ports are built into the device, increasing the flexibility and feedback functionality of the pneumatic system. The USB-C connection on the Hub works with the REV Hardware Client, allowing users to test pneumatic systems without a need for an additional robot controller. {% hint style="info" %} If there is a question that is not answered by this space, send our support team an email; ****.
