Advanced features

  • The 5225 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.
  • The concurrent f/I and f/f functions enable a scaled digital output signal in conjunction with the analog output.
  • The frequency generator function is used as e.g. a time base or clock generator.
  • Input and supply polarity reversal protection.
  • Programmable digital outputs including NPN, PNP or relay options.

Technical characteristics

  • 4 front LEDs, indicating f in active inputs (not NPN), Dig.out.1 (NPN or relay 1) and Dig.out 2 (relay 2) outputs, and a NAMUR input 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.
