德国Motrona模块FU252: 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
