BCD Output Timing Chart
A request signal from an external device (such as a Programmable Controller) is required to read BCD data.
Single Sampling Data Output
Pulse with a width of no less than 20 ms.
(no more than 50 ms.)

DATA
REQ.
Approximately 30 ms after the REQ signal rises, a sample is taken and the DATA VALID signal is output. Read the data when the DATA VALID
signal is ON.
The DATA VALID signal will turn OFF in 40 ms, and then in 16 ms, the data will go OFF.
Models with a BCD output have an open collector output configuration so that wired-OR connection is possible.
*The period between the DATA VALID signal and the
REQ signal should be no less than 20 ms max.
DATA (incl. POL and OVER)
and DATA VALID are wired-OR
processed.
The RUN, OUT5, OUT4,
OUT3, OUT2, and OUT1 sig-
nals are always output regard-
less of the status of the REQ
signal. Do not OR-wire these
signals.
