EZ-II Data Logger Technical Specifications
 

Data Logging:

  • 8 analog channels --12 bit – 0 to 5V range, 0.025% resolution
  • Corsa Data Logger provides regulated 5v power to sensors
  • 2 speed channels – 16 bit – 1 RPM to 16 kHz range
  • Adaptive threshold on speed channels – 0.1v to 5v range. Works with speed inputs as small as +0.200V or as large as +/- 120V
  • All channels use same sampling rate. User-selectable 1 to 20 samples per second for Basic; 1-50 samples per second for Professional
  • Input from optional lap beacon and “run/stop” switch
  • Internal real time clock for events
  • AutoStart configurable to trigger on any level of any channel
  • 2 alarm outputs – user configurable - trigger on any level of any channels
  • 20 or more additional channels via expansion bus

Recording time example: Corsa Data Logger standard systems provides 10 data channels; 8 analog and 2 speed. At 10 samples per second, the system can record for over 26 minutes before filling memory. After wireless download, the system is immediately ready to resume recording if desired.

Communication:

  • Small PC-mounted radio with USB interface
  • 900mHz band, 32k bps (European specification radio available)
  • 1000 foot typical range line of sight, 1/2 mile with Professional
  • All Corsa Data Logger communications are password protected


Physical, Power, Environment Requirements:

  • Small and light -- 4.5" x 3.4" x 1.3", 8.7 oz.
  • Requires power from vehicle or other battery -- 11 to 18 volts
  • Low current drain, 50mA typical
  • All memory is retained when power goes off
  • Water-resistant case and connectors
  • Operating temperature 32 deg. F to 150 deg. F


Other features:

  • 2 alarm outputs - Configurable for light or relay. 0.5A max current
  • Built-in LED’s visually indicate status – power, run, error
  • Built-in LED's for checking RPM / Speed hookup
  • Input for optional run switch and output for run light

Accessories and Expansion Modules:

  • Sensors - wide variety of ranges for speed, pressure, and position
  • EZ-AC1, 2, or 3 - Adds 1, 2, or 3 axis accelerometer data ; +/- 5g range
  • EZ-TK8 - Adds eight K type thermocouple channels, plus 2 speed channels
  • EZ-EXP8 - Adds eight analog channels, plus 2 speed channels
  • EZ-AFR - Adds 1 or 2 channels of wide-band air/fuel ratio data
  • Lap timer with trackside beacon
  • Manual “run/stop” switch
  • EZ-J1939 adds 40+ channels of SAE J1939 CAN bus data
  • EZ-POINTS - Adapter for points-type ignition systems
  • Battery kit for vehicles without 12V power systems

EZ-TK Thermocouple Interface:

  • Adds 10 channels (8 temp, 2 speed) to Data Logger capacity
  • Measurement range 32 to 2000 deg. F (0 to 1090 deg. C )
  • 12 bits (0.5 deg. F) resolution
  • Dimensions - 6.3” x 2.4” x 1.3”. Weight 7.8 oz.
  • Uses K type thermocouples with industry-standard mini 2-blade connectors
  • Built-in cold junction compensation, calibration, and linearization
  • Open thermocouple detection – goes full minus
  • Handles floating or grounded junction thermocouples
  • Withstands at least +/- 12v applied to thermocouples

EZ-ACx Accelerometer Expansion Module:

  • Adds 1, 2, or 3 channels of analog accelerometer data to Data Logger system
  • Range is plus/minus 5 g’s
  • 12 bits (.0034 g’s ) resolution
  • Dimensions 3.4" x 2.8" x 1.3", Weight 5.4 oz.
  • Easily mounts to floor or other location on vehicle
  • Adds 2 speed channels -32 bit -about 1 RPM to 16 kHz range

EZ-AFR Wideband Air / Fuel Ratio Module

  • Range 8.5:1 to 20:1 on gasoline
  • Works with all fuels (reduced life with leaded gas)

Corsa Data Logger with Compact Flash (EZ2-CF):

  • Designed for easy automatic operation in endurance or field test applications
  • Add Compact Flash (CF) memory card socket and door
  • Same case style as standard Corsa Data Logger. Dimensions are 4.4" x 4.3" x 1.3".
  • Water resistant door for CF card insertion / removal
  • Configure EZ2-CF via radio or PC
  • Up to 1 GB CF cards available
  • Typical power consumption 300mA at 11 to 18 volts
  • Included CF card reader/writer connects to your computer’s USB port

Record Time Example: A Corsa system configured for vehicle field testing includes an EZ2-CF with a 512Mb memory card and an EZ-TK8. The system provides 20 channels of data; 16 analog, 8 of which are temperatures, and 4 speed channels. Recording at 5 samples per second, this system provides over 400 hours (18 days!) of data logging capacity. Replacing the CF card in the system provides an additional 400+ hours of capacity each card. Data can be downloaded via CF card or EZ-Radio.


EZ-CAN Interface:

  • Monitor up to 40 channels (CAN ID's) on the vehicle bus
  • Configured through Data Logger systems (including EZ2-CF)
  • Compatible with SAE J1939 (heavy truck standard)
  • Data buffering and storage to match CAN data rate with sampling rate
  • Waterproof box and connectors
  • Power the entire Corsa Data Logger system from the J1939 connector
  • Custom software extensions available - please inquire

EZ-EXP8 Analog Expansion Module:

  • Adds 8 analog channels --– 12 bit A/D – 0 to 5V range, 0.025% resolution
  • Adds 2 speed channels – 16 bit – about 1 RPM to 16 kHz range
  • Provides regulated 5V power to sensors
  • Use multiple expansion modules to add additional channels
