ORDERING INFORMATION
• Code number: B3FP[1]
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.
Specify a code from below for [1].
(e.g. B3FP/UL/Q)
• Specify the specification for option code /Q
(e.g. /C01)
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.
• Orders will be shipped with default factory settings as
shown below.
(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.
• Factory default setting:
Input type: Voltage pulse
Frequency range: 0 – 1000 Hz
Pulse amplitude: 5 Vp-p
DC offset: 2.5 V
■ 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
Pulse sensing: DC coupled
Noise filter: None
Detecting level: High (2 V)
■ Voltage Pulse
Waveform: Square or sine
Input impedance: 10 kΩ min.
INPUT – Field-selectable
Open collector
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)
Voltage pulse
Two-wire current pulse
