Digital input DI (opt.)
Signal type: 20 to 30Vdc voltage signal
Input resistance: 2.7kΩ
Number of inputs: one point
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-PA communication.
Digital outputs — One point (std.) and one more
point is optionally available as follows.
Digital output DO1 (std.):
Output type: Transistor open collector
Number of outputs: One point
Output capacity: 30Vdc, 200mA maximum
Digital output DO2 (opt.):
Output type:
Solid-state relay output (non polarity)
Number of outputs: One point
Output capacity: 150Vdc, 150mA maximum
or 150Vac (peak to peak), 100mA maximum
DO1 and DO2 functions — One of the following
functions can be assigned to DO1 (std.) and/or
DO2 (opt.)
• Pulse output (available only for DO1, DO2)
Pulse rate: 3.6 to 36,000,000 pulses/hr (DO1)
3.6 to 360,000 pulses/hr (DO2)
(Over 3,600,000 pulses/hr, auto-setting)
Pulse width: 0.5 to 500ms (but less than half of
the period for 100% flow rate)
Note: The same and simultaneous pulse is not
available between DO1 and DO2.)
• Multi-range selection outputs (Note 1)
• High, High high, Low, and/or Low low alarm
outputs (Note 2)
• Empty pipe alarm output
• Digital Output Active Status (DO1 and DO2)
(Note 2)
• Preset count output
• Converter failure alarm output
Note 1: Two outputs (DO1 and DO2) are needed for
4-range switching and forward/reverse 2-range
switching.
Note 2: Normal Open (default set) or Normal Close is
selected for alarm outputs when programming.
When power failure occurs, unit will be fault to
Normal Open.
Communications output:
• HART (std.) — Digital signal is superimposed on
4–20mAdc current signal as follows:
Conforms to HART protocol
Load resistance: 240 to 750Ω
Load capacitance: 0.25µF maximum
Load inductance: 4mH maximum
• PROFIBUS (opt.)
Protocol: PROFIBUS-PA
Baud rate: 31.25kbps
Bus voltage: 9-30VDC
Consumption electric current of bus: less than 16mA
Manufacture Ident-No.: 093B
HEX
Standard Ident-No.: 9740
HEX
Slave address: 0-126 (Default address is 126)
Profile: Profile Ver.3.01 for Process Control
Devices
Function blocks: AI(Flow)×1 , Totalizer×1
LCD display:
Full dot-matrix 128×128 dot LCD display
(back–light provided)
The data on the LCD inside the converter can rotate
to 90, 180, and 270 degrees by a software, without
rotating the indicator itself. (Combined type only)
Parameter settings — Parameters can be set as
follows:
• IR Switches: Three key switches are provided to
set configuration parameters.
• Digital communication: The AF900 hand-held
terminal or PROFIBUS is needed to set
parameters.
• Zero adjustment: Zero point adjustment can be
started by pressing the switch in the converter.
• Damping: 0.5 to 60 seconds (selectable in one
second increments)
“Field re-verification”
Mag-Prover – Toshiba’s
Zero span calibration tool allows unit to be
re-calibrated and verified using an internal
software program (For more information contact
