Data Acquisition Instruments (DAQ)

Data Acquisition Device For Use With Enerchron® Test Management Software


  • Single box including Voltage, Temp & resistance temperature detector (RTD)
  • 24-bit DAQ-per-channel design
  • Wide measurement ranges
  • Fully isolated channel-to-channel design
  • No test channel-to-DAQ (data acquisition device) usage dependency
  • Easy expansion to higher channel count

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.


  • 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


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