FQ1A/FQ1V Pulse to Analog Converter
Brand: Yokogawa Electric Corporation
The FQ1A/FQ1V is a compact, front terminal connection type pulse-to-Analog converter that receives pulse-train signals and converts them into isolated DC voltage or DC current signals.
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
- Internal filter to eliminate chattering can be specified when ordering (In cases where the input frequency range is up to 100 Hz, the pulse width is 3 Milliseconds or more)
