Our DC-3 data acquisition system takes what the DC-1 and DC-2 already have, and adds to it!  Notable features include a stepper output for connecting to a stepper driver and motor for controlling a load valve.

An aux output is also capable of PWM output for controlling an eddy current brake power supply.

Features include the following:

• 2 RPM inputs
  • Can use tachometer signals from points ignition systems, electronic ignition, IR photo sensors, or hall effect sensors
• 2 Load Cell Inputs
  • For use with a wheatstone bridge type load cell (the most common S beam load cells)
  • 24 bit ADC for high resolution data
• 4 analog inputs
  • Use for pressure sensors, AFR signals, throttle position, raw voltages, and more
• 4 K-Type Thermocouple Inputs
• CAN Bus
• Stepper Output
• AUX 0-5v output
• Built-In Weather Station:  Air temperature, Barometric Pressure, Humidity
• Color coded connectors for easy installation
• Durable Anodized Aluminum Case
• USB-C connection to interface with a PC running Windows.
• Includes Precision DynoTech “RevBench” Software
  • Correction factor calculations based on user input atmosphere settings
    • STP, SAEJ1349, or Uncorrected
  • Complete data logging of all channels
    • Can start manual logging (user start and stop)
    • Automatic logging based on starting and ending RPM values
  • Data viewer to view all channels
    • View data channels over time and over RPM
  • Printing of saved tests
    • Includes max power, torque, corrections, and user-defined notes
