Programmable f/I-f/f converter 5225A

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.
• Input range:

  Frequency: 0...20,000 Hz

  Sensor types: NAMUR, tacho, NPN, PNP, TTL, S0

• Output range:

  Current and voltage output: 0...20 mA / 0...10 V

  Relay outputs: 0...20 Hz

  NPN and PNP output as f/f: 0...1000 Hz

  NPN and PNP output as generator: 0...20,000 Hz
