FU-252 Specifications
|
- High performance frequency-to-analogue and frequency-to-serial converter with excellent 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 serial format.
- Input range from 1Hz to 1MHz 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 linearisation curves
- Power supply 18-30 VDC, aux. voltage output 5V for encoder supply
- See “NT251” for 115/230 VAC supply

UF-251 Specifications
|
- High performance analogue-to-frequency and analogue-to-serial converter with excellent features and multiple conversion modes.
- Input range:-10V...+10V / 0/4...20mA
- Conversion time approx. 1ms only
- Quadrature frequency outputs HTL (A/B/Z) from 1 Hz to 100 kHz and RS422 (A,/A, B,/B, Z,/Z) from 1 Hz to 500 kHz
- Phase A/B depending on polarity of input signal, marker pulse output with programmable distance.
- Various user modes: Programmable V/F characteristics, Motorized potentiometer function, Cyclic frequency output curves etc.
- RS232 and RS485 interface for serial readout of the conversion result and other internal registers
- Adjustable floating average filter as well as operator programmable linearisation curves
- Printer mode for automatic data transfer of internal registers to a data logger or PC
- See “NT251” for 115/230 VAC supply
