MQ2 Free Range Type Pulse to Analog Converter

Brand: Yokogawa Electric Corporation

This µP built-in type converter inputs pulse train signal and converts it into voltage or current signal proportional to its frequency.
Features
  • Power Supply to Supply 12 V or 24 V to Pulse Generator is Internally Built-in
  • As Input Pulse, this Converter can Receive Either Current Pulse, Voltage
  • Pulse, Dry Voltage Contact or Open Collector Contact
  • Change of Input/Output Ranges, Setting of Input Pulse Width or Low Input Cut Point, Adjustment of Zero/Span, Moni­toring of Input/Output can be Done by Handy Terminal Even in the Field
  • If it Receives Chattering Signals, Filter can be Set Internally
