GENERAL SPECIFICATIONS

Construction: Small-sized front terminal structure

Connection: Euro type connector terminal

Housing material: Flame-resistant resin (gray)

Isolation: Input to output

DIP/rotary switches: For input calibration

(Refer to the instruction manual)

Noise filter: Chattering protection filter selectable with DIP

switches (time constant 1 msec.)

Pulse sensing: DC coupled or capacitor coupled selectable

with DIP SW

INPUT SPECIFICATIONS

Measurable frequencies: 0 – 0.01 Hz through 100 kHz; Sine

waves with frequencies lower than 0.1 Hz cannot be

detected with capacitor coupling.

Pulse width time requirement: Min. 4 μsec. for both H and L

levels

DC offset: Selectable within the maximum voltage for

respective pulse amplitude setting.

(e.g. For the amplitude 2 Vp-p with the maximum voltage

10 V, DC offset can be as low as -9 V and as high as +9 V.)

Frequency offset: Selectable up to 50 % of the full-scale

frequency.

■ Open Collector

Sensing voltage/current: Approx. 2.5 V DC @ 1mA

Detecting levels: ≤ 750 Ω / 0.7 V for ON;

≥ 3.0 kΩ / 1.3 V for OFF

■ Voltage Pulse

Waveform: Square or sine

Input impedance: 10 kΩ min.

Input amplitude: Min. 0.1 V p-p, max. 200 Vp-p

Max. voltage between input terminals: 100 V

(Max. voltage across the input terminals: 70 V for conform

with EU Directive; 30 V rms, 42.4 V peak or 60 V DC for UL

approval)
