ID : 01-000273
Size: 155 (W)⫻155 (H)⫻55 (D) mm
Weight: Approx. 800 g
(Without battery and rubber boot)
Bulletin XL120-E
Main Features
Application Examples
Wide-view TFT LCD Screen
Datum-Y adopts a color TFT
LCD screen offering a wide
angle of view,
so displayed data can be
read clearly even from angled
directions.
You can select a desired
display mode from among
Wavefor m, Digital,
Bar Graph and Waveform +
Digital.
All Channels Adopt Universal Insulated Inputs
The channels in the analog input part adopt
insulated inputs, which means that temperature
(thermocouple/resistance temperature detector)
and voltage can be set differently for each
channel.
Eleven types of thermocouples, Pt100 and
JPt100 temperature-measuring resistors, and a
voltage up to 50 V range are supported.
Detachable Terminal Block
Wiring is easy, since the terminal block
can be removed with a single action.
Built-in terminal screwdriver
Te r minal block (for 16 channels)
Compact Size
External dimensions: 155 × 155 × 55(mm)
Weight: Approx. 800 g
Easy to carry
Space Saving
The analog inputs are wired from the left, while the
power and communication lines are wired from the
right. This design makes Datum-Y a suitable option in a
narrow space.
Main Functions are Directly Accessible with Just the Push of a Button

Built-in rechargeable batteriy
The dedicated lithium ion battery enables
up to 7 hours of operation (in conditions
recommended by Yokogawa).
Rubber Boot (Standard Accessory)
Resistance to impact is improved by the use of a rubber
boot, which is removable.
Variety of Functions Facilitate Measurement and Data Acquisition
Spot Check of Acquired Data
You can check measured data
(binary) on Datum-Y right away.
Overall trend and alarm output can
be checked on the spot immediately
after acquisition.
While Datum-Y is logging data, you
can display past data and current
data in the logging review mode for
comparison and identification of
trend. (This function is available
only when binary data is acquired.)
Screen in Logging Review Mode
Calculation Function
Datum-Y is capable of four arithmetic functions (among channels, between
channels and constants, etc.), statistical operations (minimum, maximum,
average, root-mean-square and peak values from start to end of logging), and
scaling.
Alarm Function
Datum-Y can be fitted with up to four alarm output channels. One alarm can be
set for each input channel, and multiple channels can be combined freely with
AND/OR gates. You can also use the e-mail delivery function to notify specified email addresses upon occurrence or reset of an alarm.
Trigger Function
You can use the pretrigger/trigger delay function,
which is convenient when you
detect and analyze the cause of
an error. You can start to
acquire data before and after a
trigger for up to 600
measurements, respectively.
(Pre-trigger starts data
acquisition before the trigger,
while trigger-delay starts data
acquisition after the trigger)

File Split and Media Overwrite Functions
You can split a measurement data file at a specified time (hours and minutes)
while you are logging data. Furthermore, you can select the following save
options: Delete and Save to delete past measurement data and create new data
when the storage capacity of the destination storage media is full, Repeat Save
to overwrite the old data in the file during measurement, and Stop to stop the
saving. In addition, you can use the FTP function to acquire data stored in
Datum-Y without stopping measurement.
Acquisition of Large Amounts of
Data Using External Storage Media
Acquisition of Large Amounts of Data Using External Storage Media
Datum-Y lets you save data not only in its internal memory (16 MB), but
also in external storage media such as compact flash memory cards*
and SD cards* (up to 512 MB).
Data saved in these media can be copied to a USB memory* for easy
transfer to a PC.
* Use compact flash memory cards, SD cards and/or USB memory whose
compatibility with Datum-Y has been verified.
-Side-
External Trigger Input/Output
For connecting another device and synchronizing
measurements.
Digital Input/Output
For using pulse input (on one channel), logic inputs
(on two channels), and alarm outputs (on four
channels) via optional digital input/output cables
(91029).
Type II Compact Flash Slot
For saving data to a compact flash memory card
