• Single-color (red or green) and three-color (red, green, or
orange selectable) displays with a character height of 80, 120,
or 200 mm are available for a variety of applications and
locations.
• Thin design with a 39.5-mm depth for the 120-mm model is
perfect for saving space in equipment and devices.
• Decimal display including negative sign (−) display with signal
codes is possible.

2.
Only the numeral will be OFF if there is parallel input with CN1. The decimal point will be lit if there is B7A serial input with TB1.

Only the numeral will be OFF if there is parallel input with CN1. The decimal point will be OFF if there is B7A serial input with TB1.
4.
The previous statuses of A to D before LE goes low will be held. There is no relationship to the decimal point. The LE latch function will not, however, operate
at the time of serial transmission.

Note: 1.
The CN2 or CN3 Multi-digit Connector must be used for
serial transmission and dynamic control with the B7A Link
Terminal. Refer to page 5 for details. Use the CN2 and CN3
for connection with the M7E only.
2.
Use the following connectors for the connector terminals:
CN1: XG4M-2030 or equivalent
CN2 and CN3: M7E-WH@11A
Refer to
CN1 Terminal Arrangement
for the pin numbers.
Refer to page 2 for the dedicated harness.

Operation Examples of Zero Suppression
Zero suppression operates when the display is 0, RBI is low, and the decimal
point is not lit. Then low is output to RBO.
Example 1: Zero suppression is not required and the RBI input and RBO
output of each digit are open.
Example 2: 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.

External Connections
Refer to
Block Diagram
on page 4 and
Terminal Arrangement/Functions
on page 3 for external connections for each Unit.
PLC Connections
Refer to your PLC operation manual before connecting the PLC.
Static Control
Connected to C500-OD213 Transistor Output Unit
PLC
A to D,
DP, BI
Connect the PLC's output to the A to D (BCD
output), DP, and BI terminals individually.
Note:
Use separate output terminals for DP
or BI control.
Dynamic Control
Connected to C200H-OD215 (Static Mode) Transistor Output Unit
PLC
A to D,
DP, LE
•
Connect the PLC's output to the A to D (BCD
output) terminals of the rightmost digit.
•
Latch control is set with the LE1 to LE4 terminals of
the rightmost Unit.
The terminals correspond as follows:
LE1: Rightmost digit (example: 1's digit)
LE2: Second digit (example: 10's digit)
Harness connector
LE3: Third digit (example: 100's digit)
M7E-WH@11A
Note: 1.
The display colors of the three-color displays must be selected individually. LE4: Forth digit (example: 1,000's digit)
2.
In static mode, ladder programming is required for latch control.
•
By supplying power to a single display, all the displays will be
supplied with power.
•
The B7A's serial output must be connected to the SI terminal of
the rightmost TB1.
•
Use OMRON's M7E-WH@11A Harness Connectors or
equivalent to connect all Units.
•
The DP and BI terminals can be controlled by transmitting the
Harness connector
following special data
M7E-WH@11A
Hexadecimal C data: Turns ON the decimal point of the relevant
digit.
Hexadecimal D data: Turns OFF the decimal point of the relevant
digit.
Hexadecimal F data: Deletes the display (BI control) of the
relevant digit.
•
Use the B7A Link Terminal with a normal I/O delay of 19.2 ms.
PC
OUTPUT UNIT
The B7A with short I/O delay cannot be used.
(BCD output)
Note:
The display colors of the three-color displays must be selected individually.
