Input Functions
1, +, and – Inputs
When the 1, +, or – input is set to level H for the positive
logic or level L for the negative logic, the 1, +, or – display
is turned on, respectively.
Latch Input
When the Latch input is set to level H for the positive logic
or level L for the negative logic, the 1, +, or – display at the
time is maintained. (DP input is independent.)
LT (Light Test) Input
When the LT input is set to level H for the positive logic or
level L for the negative logic, the entire display turns on.
BL (Blank) Input
When the BL input is set to level H for the positive logic
or level L for the negative logic, the entire display turns off
regardless of other inputs.
DP (Decimal Point) Input
When the DP input is set to level H for the positive logic or
level L for the negative logic, the decimal point turns on.

Note 1: × indicates the display is not affected by voltage level of H or L.
Note 2: *A decimal point is displayed with any character.
Note 3: The 2-color alternate does not have the LT terminal.
(2-color Alternate Unit)
The display color is switched between red and green using the R/G (No. 6) terminal.
For other inputs, refer to the above table.
The 2-color alternate unit does not have an LT terminal.

Input Functions
A, B, C, and D (binary code) Inputs
These inputs are decimal or data
corresponding to 1, 2, 4, and 8,
respectively.
Latch Input
When the Latch input is set to level H
for the positive logic or level L for the
negative logic, the display at the time is
maintained. (DP input is independent.)
LT (Light Test) Input
When the LT input is set to level H for the
positive logic or level L for the negative
logic, the entire display turns on.
BL (Blank) Input
When the BL input is set to level H
for the positive logic or level L for the
negative logic, the entire display turns off
regardless of other inputs.
DP (Decimal Point) Input
When the DP input is set to level H for the
positive logic or level L for the negative
logic, the decimal point turns on.

Application Examples of RBI and RBO
[Ex.1] Leading zeros are also displayed. RBI and RBO outputs are
disconnected.
[Ex.2] Leading zeros on the upper three digits are suppressed. When the data
on the 1st digit is zero, 0 is displayed.
[Ex.3] Zero on the 4th digit is suppressed. Zero and decimal point are
displayed on the 3rd digit.
[Ex.4] Trailing zeros on the 2nd and 1st digits are suppressed. When the data
on the 1st and 4th digits are zero, and the decimal point on the 4th digit
is on, 0.0 is displayed with zeros on the 2nd and 1st digits suppressed.
Note: Use the RBO output only for connection to the RBI input. Do not use the RBO for
other connections.
Input and Output Functions
RBI Input
When 0 is displayed and the decimal
point is turned off, the display is
blanked by setting the RBI input to
level L.
RBO Output
The RBO output remains in level L
during zero blanking. Leading zeros
can be suppressed by connecting the
RBO to the RBI on the lower digits.
The RBO output is an open collector output.

Panel Mounting
Display units can be installed into a panel cut-out by snap t.
Assemble display units and end plates together in advance. Hold
the assembly at the end plates and push it into a panel cut-out.
Mother Board (for 4-digit display)
The mother board is intended for 4-digit display and must be
connected to four display units at once. Therefore, mount or
dismount the mother board properly according to the procedure
below.
[Installation]
Put the substrates of four display
units into the connectors on the
mother board. Insert the substrates
into the connectors, pushing the
display units on upper and lower
sides alternately.
Note: Be sure to insert four display
units at once.
[Removal]
Remove the display units, pulling the
upper and lower sides alternately. Be
sure to remove all the four units at the
same time.
CAUTION:
Never insert or remove the display
units one by one as shown. The
substrate may be damaged.
Note: For installation of the mother
board for 2-digit and 3-digit
display, perform the same
procedure.
Instructions
1. When cleaning the surface of the lter and housing, use a soft
cloth. Do not use thinner or acid to clean the surface.
2. When the display unit is mounted in a panel cut-out, do not
place a metal object or power line within 40 mm from the end
of the connector terminals (or PC board terminals) at the rear
of the display unit.
3. If the display units are subjected to voltage surges, install a
surge suppressor in the power line.
4. Use shielded cable or metal conduit for the input line. Run the
input wiring as far away as possible from high-voltage and
motor lines. Make the input line as short as possible.
5. When using display units in environments where a large
amount of electrostatic noise is generated, such as where
molding materials, powders, or uids are transferred through
pipe lines, keep the display units as far away as possible from
electrostatic sources.
6. Avoid using the display unit in a place where excessive and
frequent vibration or impact may occur.
7. Avoid using the display unit in a place where it is exposed to
corrosive gas, water or oil splashes, dust or direct sunlight, or
in a place where organic solvents are used.
8. The lter is made of polycarbonate. Make sure that machine oil
does not touch the lter.
9. If the Latch input is on when the DD3S is powered up, the
data input cannot be read correctly or wrong data may be
maintained. Do not turn on the Latch input for 0.5 sec after the
DD3S is powered up.
10. When connecting a pull-up or pull-down resistor to the input
terminals, ensure compatibility with the input resistor of the
DD3S internal circuit.
11. When the DD3S is powered up, an inrush current of 2A (10
ms maximum) ows through the internal power supply circuit.
Select an external power supply of sufcient capacity, taking
this inrush current into consideration.
12. Solder the terminal at 350°C within 3 seconds using a 60W
soldering iron. Sn-Ag-Cu is recommended when using lead-
free solder. When soldering, do not touch the control unit with
the soldering iron. Also ensure that no tensile force is applied
to the terminal. Do not bend the terminal or apply excessive
force to the terminal. Use a non-corrosive rosin ux.
