Continuous Data Output - Omron K3HB Datasheet

■ BCD Output Timing Chart
A REQUEST signal from a Programmable Controller or other external device is required to read BCD data.
Single Sampling Data Output

REQ.
MAX.MIN.
DATA
All data "High"
DATA
VALID
Approx.
30 ms
The data is set in approximately 30 ms from the rising edge of the
REQUEST signal and the DATA VALID signal is output.
When reading the data from a Programmable Controller, start
reading the data when the DATA VALID signal turns ON.
The DATA VALID signal will turn OFF 40 ms later, and the data will
turn OFF 16 ms after that.
• The K3HB BCD output model has an open collector output, so wired OR connection is possible

can be used in a wired OR.
RUN, HH, H, PASS, L, and

without a REQUEST signal.
Do not used a wired OR
connect for these signals.

DATA
All data "High"
DATA
VALID
Approx.
30 ms
Measurement data is output every 64 ms while the REQUEST signal
remains ON.
Note: If HOLD is executed when switching between data 1 and data
2, either data 1 or data 2 is output depending on the timing of
the hold signal. The data will not go LOW.
