BCD OUTPUT TIMING CHART
VIEWING ANGLE
Request signals (REQ, MAX_REQ, MIN_REQ) from an external
device (e.g. PLC) are required in order to read out BCD data.
All signals in the following charts are in the negative logic
(ON at LOW signal, as factory set).
The display is designed to provide the optimal legibility
when viewed from the angles as shown below.

When one of REQ signals (REQ, MAX_REQ or MIN_REQ) is given and
its width is between 20 and 50 ms, DATA is established and DAV output
is given in approx. 30 ms from the falling edge of the REQ signal.
Read in the data to a PLC at the timing of the DAV output signal.
DAV is turned off in 40 ms. DATA is turned off in 16 ms after that.
•
Output is provided via open collector, enabling wired-OR gate configuration
