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.

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.

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.

Safety Precautions for M7E

■Precautions for Correct Use

Display Units

Installation environment

•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.

Mounting

Connector Insertion

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

Make sure that no wire is more than five meters long when wiring.

Handling

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.

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 M7E-

01UG2-A) for the desired lighting color.

2. Take transparent polyester film (with thickness equivalent to

0.188) and cut it to the following dimensions.

3. Print solid black on the film covering all areas except the

character and so that the desired unit character is within the

character display range (with the unit character transparent).

4. Install the completed face plate into the Unit Display Unit.

Mother Board

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.

•Link the Units by snapping the

projecting tips and slots together.

•To undo the linkage, use a slotted

screwdriver as shown in the

following figure and press the upper

and lower tips while separating.

M7E Connection

•Connection of Mother Board and M7E

Note: Do not connect the Mother Board static model to the M7E-

01D@D2(-B) dynamic model, otherwise LE will be held.

•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

M7E to or disconnecting

the M7E from the Mother

Board, hold the front

panel of the M7E or the

case and be sure to apply

appropriate force on the

top and bottom of the

Mother Board alternately.
