Converter Specifications

Input signals

Analog signal — the voltage signal from detector, proportional to process flow rate.

Digital input DI (opt.)

(added when 9th 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.

Output signals

Current output:

4–20mAdc (load resistance 0 to 1KΩ)

Digital output (DO) — One point (std.) and three 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～DO4 (opt.)

(Added when 9th digit of specification code is “3”) Out put type: Solid-state relay output (non polarity) Number of outputs: 3 points

Output capacity: 150Vdc, 150mA maximum or 150Vac (peak to peak), 100mA maximum

DO functions—Four digital output function, either of the following functions can be selected.

•Totalizer pulse output

DO1 or DO2 can be selected (Forward direction pulse and reverse direction pulse can be assigned independently)

In the case of DO1

Pulse rate: 3.6 to 3,600,000 pulses/h

Pulse width:Settable within the range of 0.3 to 500ms

In the case of DO2

Pulse rate: 3.6 to 360,000 pulses/h

Pulse width: Settable within the range of 4 to 500ms

•Rage switching output

One Digital Output (DO) is used

･Single direction, 2-range switching signal ･Forward/reverse direction switching signal

Two Digital Outputs (DO) are used

･Single direction, 4-range switching signals ･Forward/reverse 2-range switching signals

•High/low limit alarm output

An alarm is output when flow rate goes above or below the set-point value

Setting range: -10 to 110% of the settable maximum range

High limit 2 points, low limit 2 points can be set At the time of alarm output, Normally Open or Normally Closed contact can be selected

•Preset point output

Contact ON when totalizer count exceeds the set value

Setting range: 1 to 99999999 count

•Converter error alarm

An alarm is output when an operation error is detected by self-diagnosis.

At the time of alarm output, Normally Open or Normally Closed contact can be selected
