VJQ2 Free Range Type Pulse to Analog Converter
Brand: Yokogawa Electric CorporationThe VJQ2 is a compact, plug-in pulse-to-Analog converter that receives pulse-train signal and converts it into isolated DC voltage or DC current signal.
The transmitter can receive either voltage pulse, current pulse, voltage-free contact signal or open-collector signal.
Features- A Withstanding Voltage of 2,000 Vac
- A Switch-selectable Input Filter for Receiving Signal Carrying a Large Amount of Chatter
- A Wide Supply Voltage Range - Supporting Both 100 V and 200 V Power Lines of AC or DC
- Close Side-by-side Mounting
