• Input span frequency

• Output span frequency

• Low-end cutout

• Non-uniform wave averaging

Input pulse sensing: DC coupled

Averaging non-uniform input waveforms: Input pulses are

divided and then multiplied so that the output pulses are

averaged.

Low-end cutout: No pulse output for certain low level of

input frequency; 0.3 – 100 % adjustable; deadband 1 %

INPUT SPECIFICATIONS

Excitation: Shortcircuit protection; approx. 440 mA (max.) at

shortcircuit

Minimum pulse width time requirement: 5 μsec.; 50 msec.

for mechanical contact (for both ON and OFF)

Minimum frequency span requirement: 20 % of the selected

input frequency range

■ Open Collector & Mechanical Contact

Input requirements (Excitation: Sensing)

5 V: Approx. 4 V / 1.0 mA

12 V: Approx. 9 V / 2.3 mA

24 V: Approx. 16 V / 4.7 mA

Resistance at ON : ≤ 200 Ω

Resistance at OFF : ≥ 200 kΩ

Detecting level: 1 V with 5 V excitation

2 V with 12 V/24 V excitation.

(Detecting voltage in the internal circuit)

For open collector or mechanical contact input, be sure to re

-adjust the voltage back to 1 V (excitation 5 V) or 2 V

(excitation 12 V/24 V) if it has been changed for other input

types.

Detecting pulse edge: OFF (input monitor LED ON) to ON

(input monitor LED OFF)

■ Voltage Pulse

Waveform: Square or sine

Input impedance: ≥ 10 kΩ

Pulse amplitude: 0.1 – 100 Vp-p (square)

1 – 100 Vp-p (sine or similar)

Max. voltage between input terminals: 50 V

Detecting level: 0 – 5 V (Detecting voltage in the internal

circuit.)

Detecting pulse state: A pulse rise detected when the input

voltage goes above the detecting level (input monitor LED

ON); a pulse sink detected when it goes below the level

(input monitor LED OFF).

■ Two-wire Current Pulse

Input resistance: Receiving resistor 100 Ω

Input range: 0 – 25 mA

Minimum pulse amplitude: 10 mA

Detecting level: 0 – 5 V

(Detecting voltage in the internal circuit.)

Detecting pulse state: The input resistor (100 Ω) converts

the current signal (0 - 25 mA) into 0 – 2.5 V. A pulse rise

detected when the voltage goes above the detecting level

(input monitor LED ON); a pulse sink detected when it goes

below the level (input monitor LED OFF).
