CAUTION

MODEL: PRU–[1][2]–[3][4]

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

scaling method. The user must be aware that it may be

inconvenient for certain types of application.

2) This unit is designed to accept at the maximum of 100

kHz, which may cause errors due to chattering in the input

pulses.

ORDERING INFORMATION

• Code number: PRU-[1][2]-[3][4]

Specify a code from below for each of [1] through [4].

(e.g. PRU-11-B/Q)

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.

• 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/S01)

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

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

transducers.
