Talon SRX

P/N: 14-838288

The Talon SRX offers the latest in smart speed controller technology compressed into a robust, compact package. This latest iteration of the popular Talon platform from Cross the Road Electronics adds support for CAN, additional communication protocols, and integrated PID control.

Users outside of FRC: Please note that you will need a HERO Development Board to field-upgrade any Talon SRX for use with CAN features.

The Talon SRX has the following new features...

• Two new sensor types for CTRE Magnetic Encoder (absolute and relative).
• Voltage Compensation Mode.  Motor Output is expressed in output volts, and Talon will modulate the output based on battery voltage measurement.
• Current Closed-Loop Mode.  Talon will servo to a target current-draw.
• User can now select the nominal forward and reverse output during Closed-Loop.  This means that if the Closed Loop Error is nonzero (or outside of the Allowable Closed-Loop Error) but the Closed-Loop calculates a motor output that is weaker than the specified nominal value, Talon will promote the motor output to the nominal value.
• Use can now specify the peak forward and reverse output during Closed-Loop.
• User can now select the Allowable Closed-Loop error so that the motor drive remains neutral even if closed-loop error is nonzero.
• Talon supports an advanced control mode called Motion Profile, that allows streaming the trajectory points of a motion profile into a Talon, while the Talon executes it.  This ensures accurate timing between trajectory points.
• Robot API supports unit scaling so sensor position/velocity and Closed-loop target position and velocity can be expressed in rotations and RPM. roboRIO Web-based config also will decode in rotations and RPM.

The Talon SRX was co-developed through a collaborative partnership between VEX Robotics and Cross the Road Electronics. Click here to learn more about this exciting partnership.

• Includes support for several communication protocols
• Onboard PID algorithms grant quick access to advanced control
• Compact, lightweight package is ideal for competitive robotics
• Used by >1000 FRC teams worldwide!

In addition to support for CAN and other advanced communication protocols, the Talon SRX includes a compilation of smaller features that add up to a robust all-inclusive motor speed controller.

• CAN and Digital IO protocols augment motor speed control with direct sensor feedback
• Onboard closed-loop PID control algorithms make complex motor control accessible to all teams
• Full aluminum case, passive cooling fins, and sophisticated internal components make fans optional
• Completely sealed enclosure prevents debris from getting anywhere it shouldn't be
• Electrically insulated components allow for direct controller mounting to a robot frame with no fear of shorting
• LED indicators blink proportionately to output speed for easier debugging
• Illuminated "Brake / Coast Calibration" button enables one-touch setting changes and calibration
• Robust embedded power & output cables will never shake loose during a match
• Built-in pockets sized for #8 nuts and zip tie grooves make rigid mounting simpler than ever
• Integrated sign-magnitude synchronous rectification reduces heat generation at full motor stall
• 15.625 kHz output switching frequency ensures smooth and precise motor control
• Plug and play support for the CTRE Magnetic Encoder Sensor making sensor feedback even easier
