1.1.2 ZN-KMX21

Easy Multi-point Data Acquisition
(1)
The ZN-KMX21 Power Sensor Station provides the measurement and recording of power
consumption at multiple points. Individual measured values are added to total sums, which can
be checked at operation sites. The station can be connected to up to 31 Power Sensor/Monitor
units, whose momentary power, integrated power, power factor, and pulse count values can be
independently recorded. Power data acquisition at operation sites now becomes easy,
contributing to enhanced energy-saving efficiency.
(2) Recording in SD Memory Card
The measured data can be recorded in the Power Sensor Station. Up to approx. 200 data
items* can be accumulated in the internal memory at the maximum load, and approx. 6800
items at the minimum load, which enables the station to continue data recording even at an
emergency network failure. The station allows its data accumulated in the internal memory to
be output to an SD memory card in CSV format without stopping measurement, thus making
continuous recording for long hours possible.
* The recordable shortest time in the internal memory is approximately 1 hour and 20 minutes.
Use an SD memory card for longer time of recording.
Network Connections
(3)
The measured values obtained from multiple Power Sensor Station units can be recorded to a
PC connected to the stations via LAN cable by using the PC software. Individual Power Sensor
Stations can be controlled from the PC to check or change their settings as well as start/stop
the recording. (Refer to "Multi Data Viewer Light Software Manual" for details.)
Online real-time control of the entire network is also possible from the PC by using Wave
Inspire ES, separately sold software.
(4) Graph Display and Data Processing Software
The data output to an SD memory card or recorded to a PC through LAN connection can be
displayed in graphs or processed online by using the PC software. The data items in different
periods can be combined or multiple station data can be displayed simultaneously side by side
on the screen. (Refer to "Multi Data Viewer Light Software Manual" for details.)
(5) Alarm Output
Alarm output terminals are provided on the Power Sensor Station. The alarm is output when
the measured power value exceeds the upper limit. This feature provides 'visualization' of the
power limit, allowing the operator to quickly handle problems.
