KFM2151

General Description
Impedance measurement system (scanner system)
Fig.1-1 shows an impedance measurement system consisting of the KFM2150,
PLZ-4W Series, and KFM2151. The load current of the fuel cell and impedance
measuring AC current flows through the PLZ-4W Series. The current signal is
passed from the PLZ-4W Series to the KFM2150. The KFM2151 scans the voltage
signal for the impedance measurement and passes it to the KFM2150 where the
impedance is measured.

1.3 Features
●
32 channel inp u t, expanda b le u p to 160 channels.
The input section consists of 32 channels per unit. The number of channels can
be expanded to 160 by using five KFM2151s. This feature is best suited to the
monitoring of each cell of the fuel cell.
●
Best for impedance meas u rement
By combining with the KFM2150 FC Impedance Meter, an impedance
measurement system for fuel cells can be configured.
●
DC v oltage meas u rement f u nction
Equipped with a DC voltage measurement function. Input voltage up to 200 V
can be measured.
●
Change the meas u rement point w itho u t changing the w iring
The KFM2151 allows arbitrary SENSING terminal numbers to be assigned to
channels (logical channels). Because the channels are logical channels,
measurement points can be changed without having to change the wiring. The
same SENSING terminal number can also be assigned to multiple logical
channels.
