MQ2 Free Range Type Pulse to Analog Converter
Brand: Yokogawa
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
