PR Electronics 5223 transmitter offers advanced features that can be configured either using a standard PC with the Loop Link communications unit or delivered pre-configured. Here are its applications and technical specifications:

Application Features

  • Frequency to Current and Voltage (f/I) Functionality: Converts frequency signals into corresponding current and voltage outputs.
  • Frequency to Frequency (f/f) Functionality: Performs pulse division or multiplication and acts as a buffer for rapid pulse trains.
  • Scale Factor: Allows scaling in all functions; supports pulse addition or subtraction using digital inputs.
  • Frequency Generator: Used as a time base or clock generator.
  • Polarity Reversal Protection: Protects inputs and supply from incorrect polarity.
  • Galvanic Separation: Ensures isolation between current/voltage outputs and inputs/supply.
  • Programmable Digital Outputs: Options include NPN, PNP, or relay outputs.
  • ATEX Units Compatibility: Supports mechanical contact inputs and NAMUR inductive proximity sensors.

Technical Characteristics

  • Front LEDs: Indicate active inputs (f1, f2), digital outputs (Dig.out.1, Dig.out.2), and programmable error status.
  • Analog Current Output: Configurable within 0–20 mA range.
  • Voltage Output: Selectable between 0–10 VDC and 0–1 VDC using internal jumpers.
  • Input Range:
    • Frequency: 0–20,000 Hz
    • Sensor Types: NAMUR, tacho, NPN, PNP, TTL, S0
  • Output Range:
    • Current and Voltage: 0–20 mA / 0–10 V
    • Relay Outputs: Up to 20 Hz
    • NPN and PNP Output (f/f): Up to 1000 Hz
    • NPN and PNP Output (Generator): Up to 20,000 Hz
