Applications

Each data acquisition device channel provides its own high resolution 24-bit DAQ, a separate per channel measurement range, and each channel is fully isolated from all other channels. This makes it possible for adjacent voltage channels to measure cell voltages as well as module, string and pack voltages at the same time (figure 1). Additionally, temperature measurement channels are independently programmable for each thermocouple type (B, E, J, K, N, R, S, and/or T) allowing any combination of temperature sensors to be used.

Advantages

data acquisition instruments (daq)

  • Breaks the traditional test channel to DAQ dependency
  • Allows measurements from any channel to be utilized by any test
  • DAQ (data acquisition device) can be placed closer to the UUT
  • Allows configuration which best suits the testing needs

Benefits

  • Modular approach
  • No limit to the amount or type of data acquisition channels
  • Allows for future expansion of the system
