Advanced Features
• The DRST-FR signal converter can be configured with OMSET software in a standard PCand the TXUN-KIT communications unit.
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.
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 to 20 mA range.
• Voltage output range is selectable between 0 to 10 Vdc and 0 to 1 Vdc by use of internal jumpers.
• Input range: Frequency: 0 to 20,000 Hz Sensor types: NAMUR, tacho, NPN, PNP, TTL, S0
• Output range: Current and voltage output: 0 to 20 mA / 0...10 V Relay outputs: 0 to 20 Hz NPN and PNP output as f/f: 0 to 1000 Hz NPN and PNP output as generator: 0 to 20,000 Hz
