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
