Overview and Features
By connecting the power monitor/sensor KM series (sold separately), the ZN-KMX21-
□
allows you to record the measured data of the power monitor/sensor (KM series) and set
various operations.
●
Display and judgment output
The display of the measured data can be switched with the
▲
and
▼
keys. Also,
you can select the measurement target of the monitoring target and set the
threshold value to output an alarm from the output terminal.
●
Data output and viewing
Measurement values can be recorded to the unit's memory and the recorded
measurement values can be stored into the SD card.
SD card : Data is in CSV format.
Measured values collected on multiple sensors can be displayed as a graph and
combined as a single file by using the PC software that can be downloaded from
the product page.

1: Only supported for KM50-C and KM50-E.
*
2: Automatically writes the data to the SD memory card when the internal memory reaches its capacity and continues recording until the SD card memory capacity reaches its limit. The
unit stops operation if there is no SD memory card inserted when the internal memory reaches its capacity. (Recording can be resumed after inserting an SD memory card and
outputting the data to it at a press of button.)
*
3: Continues the recording of the latest measured values until the internal memory reaches its capacity. (If the internal memory capacity exceeds the capacity, data is overwritten from
the oldest one in the memory.)
*
4: Output when the integrated power upper limit specified in THR mode is exceeded.
*
5: The maximum load is applied when 10 KM50-� units are connected; and the minimum load, when a single KM20-B40-FLK is connected.
*
6: When using third party SD card, please use industrial SD card (flash memory is SLC type) with high reliability and durability. Available SD card is SD standard or SDHC standard,
Class 4 or higher, (SDXC standard can not be used) You must confirm the operation of third party SD card yourself.
*
7: The vibration resistance when mounted using the ZN9-EM01-S magnets (separately sold): 10 to 55 Hz, 0.3mm double amplitude, acceleration: 20m/s2 for each in X, Y and Z
directions for 50 min. The installation place must be free from physical shock.
*
8: OMRON's XW4B-02B1-H1 connector.
*
9: This provided AC adapter must be used.
*
10: An AC adapter is provided in the ZN-KMX21 package; and a DC cable and ferrite core are included in the ZN-KMX21-A package.
