display on a totalizing counter or meter

Typical Applications

• Positive displacement flowmeters and turbine flowmeters

• Magnetic tachometers

MODEL: 10PR–[1][2]0–R[3]

ORDERING INFORMATION

• Code number: 10PR-[1][2]0-R[3]

Specify a code from below for each [1] through [3].

(e.g. 10PR-110-R/Q)

• Input frequency range (e.g. 0 – 356.7 Hz)

• Output frequency range (e.g. 0 – 1.00 Hz)

• Specify the specification for option code /Q

(e.g. /C01)

[1] INPUT

1: Dry contact (max. 100 kHz)

2: Voltage pulse (max. 100 kHz)

[2] OUTPUT 1

1: Open collector (max. frequency 20 kHz)

2: 5 V pulse (max. frequency 20 kHz)

3: Relay contact (max. frequency 2 Hz)

4: 24 V pulse (max. frequency 20 Hz)

OUTPUT 2

SPECIFICATIONS OF OPTION: Q

COATING (For the detail, refer to M-System's web site.)

/C01: Silicone coating

/C02: Polyurethane coating

/C03: Rubber coating

CAUTION

1) This unit's output waveform is not uniform due to its

scaling method.

2) Use input relays which do not cause chattering (e.g.

mercury relays). Other relays could be used only with a CR

filter, for 10 Hz at maximum.

3) Use M-System’s Model M2PRU instead of this unit in

conjunction with the pulse output from M-System’s power

transducers.
