The VJSS is a compact, plug-in high/low signal selector that selects the higher or lower of two DC input signals and converts it into an isolated DC voltage or DC current signals.
Features
  • A Wide Choice of Output Signal Range
  • Four Isolated Ports (Input, Output-1, Output-2, Power Supply and Grounding) on a Dual-Output Model
  • A Withstanding Voltage of 2,000 Vac
  • A Wide Supply Voltage Range - Supporting Both 100 V and 200 V Power Lines of AC or DC
  • Various Parameters Such as Input Range Can Be Set and Modified Using a PC (VJ77) or Handy Terminal (JHT200)
  • Close Side-By-Side Mounting
