DH5 Isolator with Square Root Extractor

Brand: Yokogawa Electric Corporation

The DH5, a nest-mounting type DCS-supported isolator, extracts the square root of 1-5 Vdc signals and converts them into isolated DC current or DC voltage signals.
Features
  • On-site zero/span adjustment and I/O monitoring etc. can be performed from the host system or a handy terminal via the communication interface
