Specications of Input, Output, and Measurement
10.2 Specications of Input, Output, and
Measurement
Basic specications
(1) Specications common to voltage, current, power measurement
Number of input
modules
Up to 8 modules (co-existence of di󰀨erent types of input modules acceptable)
Input module type U7001 2.5MS/s Input Unit
U7005 15MS/s Input Unit
Manner of input
module installation
When di󰀨erent types of input modules coexist, install the U7005 15MS/s Input Units all
together on the Ch. 1 side.
Wiring conguration
to be measured
Single-phase 2-wire (1P2W), single-phase 3-wire (1P3W),
3-phase 3-wire (3P3W2M, 3V3A, 3P3W3M), 3-phase 4-wire (3P4W)
Wiring conguration
setting
Installed input modules can be assigned to any wiring channels. (However, only adjacent
input modules can be used to the same wiring conguration).
Di󰀨erent types of input modules can coexist in the same wiring conguration.
Di󰀨erent types of current sensors cannot coexist in the same wiring conguration.
Measurement
method
Voltage/current simultaneous digital sampling with zero-crossing synchronized calculation
Sampling frequency,
sampling bit rate
U7001: 2.5 MHz, 16-bit
U7005: 15 MHz, 18-bit
E󰀨ective
measurement range
1% of range to 110% of range
E󰀨ects of conducted
radio-frequency
electromagnetic eld
For current and active power measurement, 6% of full scale or less at 3 V
(full scale means the sensor’ rated current, only when the 9272-05 is used)
E󰀨ects of radiated
radio-frequency
electromagnetic eld
For current and active power measurement, 6% of full scale or less at 10 V/m
(full scale means the sensor’ rated current, only when the 9272-05 is used)
Display range See “10.4 Detailed Specications of Measurement Parameters” (p. 203).
Measurement mode Wideband measurement mode
Data refresh interval 10 ms, 50 ms, 200 ms
The harmonic data refresh interval is specied separately.
LPF Cuto󰀨 frequency fc
U7001:
500 Hz, 1 kHz, 5 kHz, 10 kHz, 50 kHz, 100 kHz, 500 kHz, o󰀨
(The 500 kHz LPF setting uses an analog circuit.)
U7005:
500 Hz, 1 kHz, 5 kHz, 10 kHz, 50 kHz, 100 kHz, 500 kHz, 2 MHz, o󰀨
(The 2 MHz LPF setting uses an analog circuit.)
Analog LPF + Digital LPF
Add
±
0.05% of reading to the accuracy except if the LPF is set to o󰀨.
When fc is set at 500 Hz or 1 kHz, add another
±
0.5% of reading.
The accuracy specications are specied for frequencies less than or equal to one tenth
the set cuto󰀨 frequency.
The peak value is based on the LPF-processed values, whereas the peak-over judgment
uses not-digital-LPF processed values.
