Frequency divider

FT 1D-1D

  • Adjustable zero signal
  • External scaling for controls
  • HTL / TTL level converter
TTL / RS422

Frequency divider for error-free division of frequencies / pulses.

The FT frequency divider is used for error-free division of frequencies or pulses from conventional encoders, sensors, or other incremental measuring systems. Four easily-accessible DIL switches can be used
to program division ratios from 1:1 to 1:4096 as well as the desired display of the direction of rotation. A separately adjustable divider is available for the zero signal.
The module is quickly and easily mounted in the control cabinet on a standard DIN rail.
