Request a Quote
  • Programmable f/I converter
  • Programmable decimal divider / decimal multiplier
  • Programmable frequency generator
  • Relay output as option
  • Supply voltage 24 VDC
Features
  • The user programmable version has a multifunction user interface consisting of three pushbuttons and a 3-digit LED displays.
  • 3 front LEDs, indicating f.in active input (not NPN), Dig.out (NPN or relay 1) active output and a NAMUR input error signal.
  • Analog current output can be configured within 0...20 mA range.
  • Voltage output range is selectable between 0...10 VDC by use of internal jumpers.
  • Feature include input filter, contact filter and an auxiliary supply for sensor such as NAMUR and S0.
  • Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying.

Applications

  • Typical signaling devices may be pulse generators, for instance flow meters, tacho-generators or inductive sensors.
  • The f/I function is used for frequency to current / voltage conversion.
  • The f/f function is used for division or multiplication of pulses and as a buffer for fast pulse trains.
  • A frequency generator function e.g. used as a time base or a clock generator.
