GENERAL
The VJP8 is a plug-in pulse rate converter that receives contact,
voltage or current pulse from a field, and converts it into isolated
transistor-contact pulse or contactless AC switch pulse at a preset
pulse rate. The VJP8 can also be used as a pulse signal repeater
by setting the pulse rate and pulse width type.
• Either pulse output or communication function (RS-485) is
selectable as Output-2.
•
Various parameters can be set and modified using a PC
(VJ77 (sold separately)) or Handy Terminal (JHT200 (sold
separately)) and the like.
