DQ0 Free Range Type Analog to Pulse Converter

Brand: Yokogawa Electric Corporation

The DQ0 is a nest-mounting type DCS-supported Analog-to-pulse converter that receives DC current or DC voltage signals, and converts them into pulse-train signals.
Features
  • Ranges, output pulse width, low output cut point, zero points and spans, Input/Output monitoring can be set and modified using a Handy Terminal (JHT200)
