WR5A/WR5V Free Range Type RTD Converter
Brand: Yokogawa Electric Corporation
The WR5A / WR5V is a compact, front terminal connection type signal conditioner that is connected to an IEC/JIS-standard resistance temperature detector (RTD) to convert temperature signals into isolated DC current or DC voltage signals.
Features- Selection of input type, input range setting, burnout setting, output adjustment, I/O monitoring, and loop back test can be made using the optional parameter setting tool (VJ77) or handy terminal (JHT200)
- For the Fahrenheit display, specify the option "/DF"
- Available for the combination with safety barrier (BARD700)
- WR5A and WR5V are also available in 2,000 Vac voltage withstand specifications
