471C
BCD output (Digital output)
Refer page 9 for "Wiring method" of this manual for the connector arrangement.
The measurement input and the BCD output are insulated.
Output
Open collector Sink type 、 Contact capacity DC30V10mA
Data BCD ６ digits display １ output ON(Negative logic), OFF(Positive logic)
Over （ OVER) Exceeds 999999, output ON(Negative Logic), OFF(Positive Logic)
Decimal point （ DP1 to 4) Output in correspond to the display of decimal point
ON(Negative logic), OFF(Positive logic)
Polarity (POL) ＋ OFF(Negative logic), ON(Positive logic)
Logic switching
Logical setting of Data, Over, Decimal point and Polarity can be set
to switch.
Synchronization signal
（ SYNC)
Pulse output become ON approx. for 10ms
Read the data at good SYNC rising time.
BCD output cycle Approx. 100ms
Control input
Input current Less than 1mA, OFF(H Level)=3.5 to 5V, ON (L Level)=0 to 1.5V
BCD_Latch
（ BCD_LATCH ）
When BCD_Latch pin is short circuited with DATA COM or set to L level,
only BCD is retained. Display is done continuously.
Data enable
（ OUTPUT ENABLE ）
When data enable pin is released (OFF), output data (OVER
INCLUDED) is obtained.
When data enable pin is shorted with DATA COM pin or set to L level,
data (OVER INCLUDED) becomes OFF state, SYNC output is prohibited,
and the connect to the system data bus becomes easy. (Display is not
retained).
