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.

[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.

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.

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 lead­free 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.

[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 connecter 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 a 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 acrylic.

9. If the Latch input is on when the DD48 is powered up, the
data input cannot be read correctly or wrong data may be
maintained. Do not turn on the Latch input until at last 0.5 sec
after the DD48 is powered up.

10. When the DD48-F01 is powered up, an inrush current of 0.5A
(10 ms maximum) and when the DD48-F31 is powered up,
an inrush current of 0.5A (10 ms maximum) ows through the
internal power supply circuit. Select an external power supply
of sufcient capacity, taking inrush current into consideration.

11. When connecting a pull-up or pull-down resistor to the input
terminals, ensure compatibility with the input resistor in the
DD48 internal circuit.

Input and Output Function

A, B, C, and D (binary code) Input

A, B, C and D are binary-coded decimal inputs corresponding to 1, 2,
4 or 8.

Latch Input

When the Latch input is set to level L, the display at the time is
maintained. (DP and BI inputs are independent.)

DP (Decimal Point)

When the DP input is set to level L, the decimal point turns on.

BI (Zero Blanking Input)

When the BI input is set to level H with 0 displayed, the display is
blanked.

BO (Blanking Output)

The BO output goes to level H during zero blanking. Leading zeros can
be suppressed by connecting the BO to the BI on the lower digits.

Note:
× indicates the display after inputting the Latch signal is maintained regardless of
the voltage level of H or L.
∆

indicates the display is not affected by voltage level of H or L.

DP (decimal point) turns on when the DP input signal is in level L.
