Check that the model and specifications indicated on the
nameplate attached to the main unit are as ordered.
(2) Packaged Items
Check that the package contains the following items:

GENERAL
This plug-in type pulse to analog converter receives contact
pulse, voltage pulse, or current pulse from the field and converts
the signal into isolated DC current or 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
modified using a PC (VJ77) or Handy Terminal (JHT200 and
the like).
