Programmable f/I-f/f converter 5223B

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.
• Input range:

  Frequency: 0...20,000 Hz

  Sensor types: NAMUR, contact

• 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

Note

• Not suitable for new installations requiring certification to the latest ATEX standards - see ATEX certificate KEMA 04ATEX1001 for details.
