| † | As of Summer 2024, orders made from REV Robotics will ship with the version of the Pneumatic Hub that features Latching WAGO Connectors on the Main power Input and CAN terminal blocks. | | :-: | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | †† | If using a ferrule, we recommend using square or hex shaped crimps. | {% hint style="info" %} It is recommended to use a 20A fuse or circuit breaker with the Pneumatic Hub if using a compressor with higher peak current draw, such as the CP26 or the Thomas 405ADC38. {% endhint %} {% hint style="warning" %} Double-check the specifications of your desired compressor before connecting it to the Pneumatic Hub. Compressors that have an inrush current higher than the compressor switch MOSFET can handle will damage the Pneumatic Hub on start up. The Pneumatic Hub is not compatible with the 215 series of Thomas compressors. {% endhint %} ### Solenoid Channel Specifications
