  • 3 isolated analog input channels, 50 kS/s per channel simultaneous sample rate
  • 22 Arms continuous, ±30 Apeak input range, 24-bit resolution (AC signals only)
  • Designed for 1 A/5 A nominal CTs
  • Up to 300 Vrms Channel-to-Earth and 480 Vrms Channel-to-Channel CAT III isolation
  • Ring lug connectors for up to 10 AWG cables
  • -40 °C to 70 °C operating temperature, 5 g vibration, 50 g shock

The NI 9246 current input module is a three channel 22 Arms module designed to support direct ring lug connectivity to three-phase high-current measurements of 1A and 5A current transformers (CTs). The NI 9246 is optimized for power, energy, and industrial applications that require continuous AC measurements up to 22 Arms, ±30 Apeak, and withstand over 1250 Arms for one cycle.

The safety features, certifications, input ranges, overvoltage ranges, and connectivity will help engineers with applications such as:
  • Power quality monitoring and metering
  • Utility pole-mounted smart switches
  • Utility pole-mounted smart grid reclosers
  • Substation merging units
  • Industrial machine measurements
    • Health monitoring
    • Predictive maintenance and prognosis
  • Phasor Measurement Units (PMUs)
  • General purpose AC current testing
