概述

The NI 9242 C Series analog input module has a full measurement range of 250 Vrms for high-voltage measurement applications such as phasor measurements, power metering, power quality monitoring, standard potential transformers, and motor test. It supports standard service levels up to 250 Vrms L-N and 400 Vrms L-L as well as standard 120 V PT secondaries. You can also perform transient and harmonic analysis with high-speed simultaneous sampling at 50 kS/s per channel. 

The NI 9242 offers three channels for measurements between the signal and the neutral channel, and the neutral channel provides measurements between the neutral terminal and the chassis ground. With this configuration, you can connect single- or three-phase measurement configurations such as WYE and delta. If you are developing power monitoring, metering, or quality analysis applications, consider the NI LabVIEW Electrical Power Suite, which is compatible with both NI CompactRIO and CompactDAQ systems. 

You can incorporate the NI 9242 and NI 9244 into systems to meet standards such as IEC 61010-1, C37.90 and C37.60, IEC 60255-22-(1:7), IEC 60255-1, C37.188 Class M and P, EMC section of IEC 60870, EMC sections of IEC 61850, IEC 61000-4-30 Class S, and IEC 61000-4-7. Note that with the exception of IEC 61010-1, these standards are system-level standards and the system as a whole has to be designed to these standards.
