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.

Remarks
The "1" display is retained
by the LE signal.
The "5" display is retained
by the LE signal.

• Using the latch input (LE) terminal for each Unit, the data input terminals (A to D) can be used in common yet still enable display on each Unit
(example of a 3-digit dynamic-output model with positive logic).
