National Instruments 783589-01 C Series Current Input Module 

National Instruments part number 783589-01 is an identifying part number for the NI 9247, a C Series Current Input Module with 3 Differential Analog Input Channels, 24 bits Analog Input Resolution and AC Coupling. The National Instruments 783589-01 is a Current Input Module designed for 1 A and 5 A nominal CTs. It features a three-channel design, allowing for direct ring lug connectivity to current transformers. With a range of 50 Arms, this module is ideal for energy, power, and industrial applications that require continuous AC measurements. These applications include industrial machine measurements, substation merging units, power quality monitoring, and power metering. 

Each channel of the NI 783589-01 module operates in complete isolation from earth ground and other channels. With isolation ratings of 480 Vrms between channels and 300 Vrms to earth, it is ideal for direct measurements of current at line voltages up to 277 V/480 V. However, this current input module is designed for AC measurements only and does not measure DC currents. When making frequency-specific measurements such as phasor measurements, harmonic analysis, or fundamental line frequency amplitude measurements, the DC value is ignored. 

These measurements can be performed using algorithms provided by the National Instruments LabVIEW Electrical Power Suite. Although the NI 783589-01 cannot measure DC inputs, excessive DC components in the input currents will saturate the internal transformer and cause erroneous measurements. When using this device to measure current indirectly through a current transformer, the transformer blocks continuous DC currents from reaching the device inputs. However, temporary offsets of the AC signal can still occur.
