PULSE ISOLATOR

(built-in excitation; rotary encoder use)

Functions & Features

• Galvanically isolating two pulse rate signals from a rotary

encoder

• Various outputs (relay, open collector, voltage pulses and

RS-422 line driver pulse)

• Different I/O specs can be specified

• Converting RS-422 line driver pulse input into an open

collector pulse

• Excitation

• Isolation up to 2000 V AC

• High-density mounting

Typical Applications

• Isolating field pulse signals in order to reduce noises

MODEL: RPPD–[1][2][3][4][5][6][7]–[8][9]

ORDERING INFORMATION

• Code number: RPPD-[1][2][3][4][5][6][7]-[8][9]

Specify a code from below for each [1] through [9].

(e.g. RPPD-DD4AA3N-R/CE/Q)

• Output pulse width (e.g. 75 msec.)

• Use Ordering Information Sheet (No. ESU-1693). Default

setting will be used if not otherwise specified. Refer to the

factory default setting.

• Specify the specification for option code /Q

(e.g. /C01/S01)

[1] INPUT 1

A: Dry contact

B: Voltage pulse (Specify sensitivity)

C: 5 V pulse (sensitivity 2 V)

D: 12 V/24 V pulse (sensitivity 5 V)

H: Two-wire current pulse

J: RS-422 line driver pulse

[2] INPUT 2

Must be the same code as the one chosen for Input 1.

[3] EXCITATION

1: 5 V DC @ 120 mA

4: 12 V DC @ 60 mA

7: 24 V DC @ 25 mA

Excitation is not provided with input code J, but select code

1.

[4] OUTPUT 1

A: Open collector (max. 100 kHz)

M: 5 V pulse (max. 100 kHz)

N: 12 V pulse (max. 100 kHz)

P: 24 V pulse (max. frequency 50 kHz)

H: High power photo MOSFET relay (max. 20 Hz)

(Option /CE Not available)

J: RS-422 line driver pulse (max. 100 kHz)

( ) = Max. frequency

[5] OUTPUT 2

A: Open collector (max. frequency 100 kHz)

M: 5 V pulse (max. frequency 100 kHz)

N: 12 V pulse (max. frequency 100 kHz)

P: 24 V pulse (max. frequency 50 kHz)

J: RS-422 line driver pulse (max. 100 kHz)

The max. frequency is in parentheses.

■ OUTPUT COMBINATIONS

The table below shows the selectable type of Output 1 for

each Output 2 type.

With the Output 2 other than code A, the Output 1 must be

the same type.
