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.

2. If the input terminals are open when the power supply is
turned ON, the voltage between the input terminals will not
be stable, the LE terminal may go high, and the M7E may
show unexpected displays. When you turn ON the power
supply, we recommend that you either set the LE terminal to
low or input a signal to the specified terminals from the host.

Example of Zero Suppression Usage: Description Using
Negative Logic Model
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: 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 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 @@.)
Note: Use RBO output for the RBI input connection only.
Dimensions
Note: All units are in millimeters unless otherwise indicated.
