NTC-7X-FRW: Non-Isolated Frequency Window Converter          specsheet  

  • DIN-Rail Mount (small size)
  • Industry Standard Output: 4-20 mA, 1-5 VDC, more
  • Wide Input Frequency Ranges (from 5 Hz to 10 KHz)
  • Built-in Scaling Option for Further Flexibility
  • 24 VDC and 12 VDC Supply for Open Collector Input or Dry Contact Input
  • Easy Field Calibration (Typ. calibration time < 2 min. using handheld meter only)
  • Power: 24 VDC

  • CSA and NRTL Approved (LR 51078)

The NTC-7X-FRW is a microprocessor controlled frequency to analog output converter that is easily field configurable (see Calibration). A Start and End adjustment determines the 0% input frequency and the 100% input frequency. Hence, a frequency range that is not zero based can be extracted and converted. An optional scaling input allows for output scaling.

  • Operating Temperature: -40 Deg.C. to +50 Deg.C
  • Temperature Effects: 0.5% max., 0.2% typ. (for 40 Deg.C. change)
  • Loop Drive: Max. 1000 Ohms at 20mA
