WA5A/V Distributor with Square Root Extractor
Brand: Yokogawa Electric Corporation
The WA5A/WA5V is a compact, front terminal connection type distributor that is used in combination with a two-wire transmitter, and extracts the square root of 4 to 20 mA DC input signals from the transmitter and converts them into isolated DC current or DC voltage signals.
Features- Zero/span adjustment, I/O monitoring can be made using the optional Parameter Setting Tool (VJ77) or Handy Terminal (JHT200)
- Dual output and 2,000 Vac withstand voltage specifications are available
