Model LF232*F converter
Input signals
Analog signal — the voltage signal from detector,
proportional to process flow rate.
Digital input DI (opt.)
(added when 9
th
digit of specification code is ”3”)
Voltage level: High level 20 to 30 V dc
Low level 2 V dc or less
Input resistance: 2.7 kΩ
Number of inputs: 2 points (DI1 and DI2)
DI functions:
For digital input function, either of the following
functions can be selected.
• Range switching
One Digital Input is used: switching between large
and small ranges of forward/reverse, 2-range
measurement.
Two Digital Inputs are used: switching between
ranges of single direction, 4-range measurement.
• Totalizer control input
Totalizer Start/Stop control or Reset/Start
•Output hold input
Fixed with set value for current output and pulse
output (loop check)
• Zero adjustment
Starts zero adjustment (on-stream at zero flow rate)
when DI voltage level goes low after remaining
high for 10 to 20 seconds.
