WH5A/WH5V Isolator with Square Root Extractor
Brand: Yokogawa Electric Corporation
The WH5A/WH5V is a compact, front terminal connection type isolator that extracts the square roots of 1-5 Vdc signals and converts them into isolated DC current or DC voltage signals.
Features- Low cut point setting, zero/span adjustment, I/O monitoring, etc 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
