Description
PR 5223A Programmable f/I-f/f converter is a type of frequency converter which converts frequency to Current, voltage, NPN/PNP/relays.
Advanced features – 5223 Frequency Converter
- The 5223 transmitter can be configured with a standard PC and the Loop Link communications unit, or delivered fully configured.
Application of PR 5223A Programmable f/I-f/f converter
- 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.
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 HzSensor types: NAMUR, tacho, NPN, PNP, TTL, S0, contact
- Output range:Current and voltage output: 0…20 mA / 0…10 VRelay outputs: 0…20 HzNPN and PNP output as f/f: 0…1000 HzNPN and PNP output as generator: 0…20,000 Hz
