Converter
Input signals:
Analog signal:
The voltage signal from detector.
Proportional to process flow rate
Digital input DI:
Signal type:
Input resistance: 2.7kΩ
Number of inputs: one point
Note: DI cannot be used with the Modbus
communication.
DI function:
One of the following functions can be assigned
to the optional DI signal.
Range switching
Selects either the higher or lower range in the
unidirectional or bidirectional
2-range setting.
Totalizer control
Starts and stops the built-in totalizer.
Fixed-value outputs
Outputs fixed-values for current and pulse
outputs.
Zero adjustment
Executes zero adjustment (on-stream at zero
flow rate).
Output signals:
Current output:
4-20mAdc (load resistance 0 to 750Ω)
Note: The current output cannot be used with
the
PROFIBUS
communication.
Digital outputs:
Two points are available as follows.
Digital output DO1:
Output type: Transistor open collector
Number of outputs: One point
Output capacity: 30Vdc, 200mA maximum
Note: DO1 cannot be used if Modbus
communication connection is 3
lines.
Digital output DO2:
Output type: Solid-state relay output (non
polarity)
Number of outputs: One point
Output capacity: 150Vdc, 150mA maximum
Note: DO2 cannot be used with the Modbus
communication.
DO1 and DO2 functions:
One of the following functions can be assigned
to DO1 and/or DO2.
20 to 30Vdc voltage signal
and
Modbus
or 150Vac (peak to peak),
100mA maximum
