FM260*: Quadrature Frequency and Impulse Multiplier

[PDF manual]
  • This universal impulse and frequency multiplier provides one encoder input and one encoder output, both using channels A,  /A,  B,  /B,  Z,  /Z  with programmable levels and characteristics.
  • The unit provides error-free multiplication of an input  frequency by a proportional factor F1 and a reciprocal factor F2, both adjustable in a range of 0.0005 to 9.9999. The result appears at the frequency output :
    Multiplication of encoder impulses

    More properties:

  • Index and marker pulse generator: The unit generates an index pulse with a programmable impulse distance, which – if required – can be synchronized with the input marker pulse.
  • All operation modes provide error-free frequency conversion, with full consideration of the A / B phase and direction of the quadrature signals, therefore no cumulative errors, even with continuous change of directions and vibrations.
  • Max. frequency 1 MHz on input and output, Power supply 18 – 30 VDC
  • RS232 interface and USB port, optional PROFIBUS-DP interface available
