    Signal Converter Frequency  to Analogue
    (Voltage, Current)) and to Serial RS 232


    DZ 266*: Signal Converter (Impulse Input)
    DZ 276*: Signal Converter (Sine-Cosine Input)

  • Multifunctional f-V and f-I converter module with fast response time and many programmable features for conversion of frequencies to voltage, to current or to serial data format
  • For DZ266:
    Universal impulse inputs for use with single channel signals (A only),
    quadrature signals (A, B, 2x90°) or differential TTL / RS422 signals A,  /A, B,  /B
  • For DZ276:
    Inputs for encoder lines sin+ / sin- / cos+ / cos- with 1 Vpp format
  • Common features:
  • Analogue outputs +/- 10 V (polarity represents direction of rotation) and
    0/4 – 20 mA, resolution 14 bits
  • Wide operating range:  0.1 Hz to 1 MHz (DZ266) respectively 500 kHz (DZ276)
  • Setup by means of the front keys and LCD menu, or by  PC
  • Scalable LCD display for indication of  the actual input frequency and the operating state
  • Serial RS232 interface
  • Power supply 24 VDC, auxiliary output +5V for supply of encoders
  • DIN rail mounting
  • For 115/230 VAC supply see accessories

Converter Frequency-Analogue-Serial RS232


    FU 252*: Signal Converter Frequency to Analogue
    (Voltage, Current) and to Serial RS 232 / 485

  • High performance frequency-to-analogue and frequency-to-serial converter with outstanding features and multiple conversion modes.
  • The unit can convert all frequencies, but also the sum, the difference, the product or the ratio of two frequencies to analogue and to serial format.
  • Wide input range from 1 Hz to 1 MHz for full scale output
  • Input accepts quadrature encoder signals with TTL/RS422 format or with HTL level (A,B) as well as single channel signals from sensors with PNP or NPN or Namur output
  • Analogue outputs +/- 10 V (polarity represents direction of rotation) and
    0/4 – 20 mA, resolution 14 bits
  • Serial RS232 and RS485 interface for read-out of  the actual input frequency
  • Conversion time only 1 msec., therefore also suitable as a tacho replacement
  • Accuracy 0.1%
  • Easy to set up by simple TEACH procedure, or by PC (operator software included)
  • Adjustable floating average filter to smooth output swings with unsteady input frequencies
  • Free programmable linearization curves
  • Power supply 18-30 VDC, aux. voltage output 5V for encoder supply
  • For 115/230 VAC supply see accessories

Frequency-to-Voltage Converter f/V

    Please note that also some of our Speed Indicator Units are suitable for conversion
    from frequency to analogue and from frequency to serial (see “Tachometers”)
