FQ2A/FQ2V Free Range Type Pulse to Analog Converter
Brand: Yokogawa Electric Corporation
The FQ2A/FQ2V is a compact, front terminal connection type pulse-to-Analog converter that receives pulse-train signals and converts them into DC voltage or DC current signals proportional to the frequency.
Features- With built-in 12 V or 24 V power Supply for Pulse Transmitter Inputs
- Input pulse Types Include Current pulse, Voltage Pulse, Non-voltage Contact and Open Collector Contact
- I/O Range, Input Pulse Width and Low Cut Point Setting, Zero/Span Adjustment and I/O Monitoring Can be Made On-site, using the Optional Parameter Setting Tool (VJ77) or Handy Terminal (JHT200)
- Internal Filter Can be Set to Eliminate Chattering (In Cases Where the Input Frequency Range is Up to 100 Hz, The Pulse Width is 3 Milliseconds or More)
