GENERAL

This plug-in type converter is used in combination with

transmitters which send displacement information of regulator

valves by resistance change signals from a potentiometer, and

converts the resistance change into isolated DC current or DC

voltage signals.

Output-2 can be selected from DC voltage signal, DC current

signal, communication function (RS-485), or alarm output (2

relay contacts).

Various parameters such as input range can be set and modied

using a PC (VJ77) or Handy Terminal (JHT200 and the like).
