Data Storage Unit
The Data Storage Unit collects and acquires measurement values and profiles from the
Sensor Controller installed on site, and can save this data to Memory Card. Data saved
on Memory Card can be easily loaded to a PC for use in data analysis and operations.
Measurement conditions for up to 4096 banks (16 banks x 256 files) can be registered to
an inserted Memory Card as an external bank for the Sensor Controller. Also, thresholds
can be set for data currently being logged and used as alarm output functions.
System Configuration
Data on the Data Storage Unit can
be easily captured to a PC by serial
communication, a USB connection
or by directly reading the Memory
Card.

Mounting and Connecting Devices
This section describes installation of the Data Storage Unit.
Cautions Regarding the Mounting Orientation
•Do not block the ventilation holes at the top and bottom of the Data Storage Unit body. Doing
so will cause heat to build up inside and result in a malfunction.
•When the temperature inside the control panel exceeds the ambient temperature of 50°C,
provide forced-air cooling or more space at surrounding areas, or improve air circulation to
lower the ambient temperature to 50°C or less.
To improve heat radiation, install the Data Storage Unit only in the
orientation shown below.
Do not install the Data Storage Unit in the following orientations:
