Thermocouple Interface

Allows up to 8 K-type thermocouple channels to be logged by the VBOX with 100 samples per second.

  • Direct K-type thermocouple connection
  • 100 Hz logging
  • Individual channel status LEDs
  • Supports standard and extended CAN frames
  • Individual Cold Junction Compensation sensor for each channel
  • Timer controlled transmission or polled response

How does it work?

The VBOX Thermocouple Interface (TC8-V2) measures 8 thermocouple inputs with 100 samples per second and provides a CAN output as a standalone or RACELOGIC based CAN module.

It is primarily designed to connect to a VBOX GPS data logger and log thermocouple data along with the normal channels of VBOX data. It works from any power supply from 6 V up to 30 V.

The usable measuring range of the Thermocouple Interface is -200 °C to +1300 °C. The unit uses a 24-bit ADC.

The unit can be used in standalone timed mode or in conjunction with other RACELOGIC modules such as the Analogue Input (ADC03) or Vehicle CAN (CAN02) interface.
