ORDERING INFORMATION

  • Code number: B3FP[1] Specify a code from below for [1]. (e.g. B3FP/UL/Q)
  • Specify the specification for option code /Q (e.g. /C01)
  • Orders will be shipped with default factory settings as shown below.
  • Factory default setting: Input type: Voltage pulse Frequency range: 0 – 1000 Hz Pulse amplitude: 5 Vp-p DC offset: 2.5 V Pulse sensing: DC coupled Noise filter: None Detecting level: High (2 V) INPUT – Field-selectable Open collector Voltage pulse Two-wire current pulse [1] OPTIONS (multiple selections) Standards & Approvals blank: CE marking /UL: UL approval, CE marking Other Options blank: none /Q: Option other than the above (specify the specification) SPECIFICATIONS OF OPTION: Q COATING (For the detail, refer to M-System's web site.) /C01: Silicone coating /C02: Polyurethane coating /C03: Rubber coating (UL not available) GENERAL SPECIFICATIONS Construction: Small-sized front terminal structure Connection: Euro type connector terminal (applicable wire size: 0.2 to 2.5 mm2, stripped length 8 mm) 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)
