Omron M7E-01DRD2 New models with blanking function added to the sery Datasheet

Digital Display (14 mm)
M7E
New Models with Blanking Function Added
to the Series
• Single-color (red or green) and two-color (red or green
selectable) displays with a character height of 14 mm are
available for a variety of applications and locations.
• Miniature design with a 43-mm depth is perfect for saving space
in equipment and devices.
• Wide-range power supply from 12 to 24 VDC.
• Negative sign (−) display with signal codes is possible for
Decimal-display Models.
• Models with zero suppression function available.
Model Configuration
■ Unit Configuration

■ Accessories (Order Separately)
Note: 1. Models with zero suppression are blank only when the display is 0
and the decimal is OFF by wiring as shown on page 12.
2. Models with blanking enable turning OFF a user-specified display
(0 to 9, a to f) by inputting a signal to the blank input terminal.
3. The symbol in the box (@) indicates the code for the display
contents. Refer to page 13.

Example of Zero Suppression Usage: Description Using
Negative Logic Model
4th digit
3rd digit
2nd digit
1st digit
Example 1
The zero suppression function operates when the display is 0, RBI is
low and the decimal point is not lit.
Example 1: The RBI input and RBO output of each digit are open
when zero suppression is not being used.
Example 2
Example 2: Wired as shown to display only 0 for the rightmost digit
when zero suppression is being used.
Example 3: Zeros are suppressed only for the digits on the left of
the digit where the decimal is lit when both zero
suppression and a decimal point are being used.
Example 3
Example 4: Zeros are suppressed to the right of the first digit below
the decimal point when both zero suppression and a
decimal point are being used. If the first-to-fourth-digit
values are all 0 and the decimal point is lit at the fourth
digit, 0.0@@ will be displayed. (There is no data in @@.)
Example 4
Note: Use RBO output for the RBI input connection only.

Safety Precautions for M7E
■ Precautions for Correct Use
Wiring and Connections
Make sure that no wire is more than five meters long when wiring.
Display Units
Handling
• Use the Unit in locations that are not subject to organic solvents
(thinner, benzene, etc.), strong alkali, strong acid, sunlight, and
corrosive gases.
• These Display Units are designed for indoor use only.
Visibility may be significantly reduced if the Unit is used outside or
in locations where the ambient brightness exceeds the brightness
of the M7E. The product is not drip-proof. Use the product where it
will not be subject to water or oil splashing.
• Use the Units in areas not subject to vibration or shock in excess of
specifications.

Projecting tip
Procedure for Making Face Plates for
M7E-01 Unit Display Unit
Custom face plates can be made according to the following
guidelines.
1. Prepare a blank Unit Display Unit (M7E-01UR2-A or M7E01UG2-A) for the desired lighting color.
2. Take transparent polyester film (with thickness equivalent to
0.188) and cut it to the following dimensions.
Slot
Character display range
• Link the Units by snapping the
projecting tips and slots together.
There are projecting tips made of resin on the side of each Display
Unit. Be sure not to drop the Display Unit, otherwise the projecting
tips may break.
• To undo the linkage, use a slotted
screwdriver as shown in the
following figure and press the upper
and lower tips while separating.

character display range (with the unit character transparent).
4. Install the completed face plate into the Unit Display Unit.

When inserting the connector,
make sure that the UP arrow is
pointing upwards.

• When the End Plates are linked,
the entire set can be quickly
mounted and fastened to a
panel. Confirm that the links
between units and End Plates
are secure, and then securely
fasten the End Plate tips to the
panel.
Wiring and
Connections
Secure the cable and lead
wires with the panel so that no
excessive force will be
imposed on the input
connector or power supply
terminals.

• When using the M7E-01@@P2(-B) positive logic standard model, a
pullup resistor may be required. Check the output circuit of the
connecting device and use a pull-up resistor if necessary.
• All M7E models used on a single Mother Board must be identical.
Connecting or Disconnecting the M7E
When connecting the
