  3. Accessories


Advanced features

  • The 5223 transmitter can be configured with a standard PC and the Loop Link communications unit, or delivered fully configured.

Application

  • The f/I function performs frequency to current and voltage conversion.
  • The f/f function can be used for pulse division or multiplication and as a buffer collecting fast pulse trains.
  • A scale factor may be entered in all functions. Using both digital inputs, pulse addition or subtraction are possible.
  • The frequency generator function is used as e.g. a time base or clock generator.
  • Input and supply polarity reversal protection.
  • Current and voltage output signals galvanically separated from the supply and the inputs.
  • Programmable digital outputs including NPN, PNP or relay options.
  • ATEX units have input for mechanical contact and NAMUR inductive proximity sensor.

Technical characteristics

  • 5 front LEDs, indicating f1 and f2 active inputs (not NPN), Dig.out.1 and 2 active outputs, and a programmable error signal.
  • Analog current output can be configured to any current within 0...20 mA range.
  • Voltage output range is selectable between 0...10 VDC and 0...1 VDC by use of internal jumpers.
