Data Acquisition and Control Interface (including computer-based instrumentation for 2x current inputs and 2x voltage inputs)

Data Acquisition and Control Interface (including computer-based instrumentation for 2x current inputs and 2x voltage inputs)

The Data Acquisition and Control Interface (DACI) is versatile and complete device in an A4 module used for measuring, observing, and analyzing electrical and mechanical parameters in electric power systems and power electronics circuits.


Auxiliary power:

  • Input voltage: 24 V/50 – 60Hz
  • Input current: 0.4 A (max.)




Insulated Voltage Inputs:

  • Number of input channels: 2
  • Input range: (Low / High Scales): -80 – +80 V/-800 – + 800 V (user-selectable through software)
  • Impedance (Low / High Scales): 326.6 kΩ/3.25 MΩ
  • Bandwidth: DC to 65 kHz (-3 dB)
  • Accuracy: 1% (dc to 10 kHz)
  • Insulation: 800 V between input channels, 400 V versus ground
  • Maximum Voltage (Any Terminal vs GND): 283 V AC/400 V DC
  • Measurement Category: CAT II (283 V AC/400 V DC versus ground)

Insulated Current Inputs:

  • Number of input channels: 2
  • Range (Low/High Scales): -4 – +4 A/-40 – +40 A (25 A rms)
  • Impedance (Low/High Scales): 5 mΩ/50 mΩ
