<Analog output control>
The analog output control function calculates the analog output value corresponding to a measurement value by setting
the upper/lower limit of the measurement value, and controls the output. In addition, setting the upper/lower limit value of
analog output enables to change the output range.
The measurement value is selected from the measurement items in Energy Measuring Unit Extension model for same
voltage system (Model: EMU4-A2), Energy Measuring Unit Extension model for different voltage system (Model: EMU4-
VA2), or Energy Measuring Unit Extension model for analog input (Model: EMU4-AX4) that is connected to the control unit.
*The measurement items measuring integrated values are not selectable.
*The following chart shows a measurement value and analog output value with positive gradient. It is possible to set a chart
with negative gradient.
Caution
<Notes about measurement value>
When a scaling value measured by the analog input unit (Model: EMU4-AX4) is used as a measurement value, the
scaling value must be set with the optional small type display unit (Model: EMU4-D65).
For details on the scaling value, refer to
Energy Measuring Unit Extension Model for
Analog Input User’s Manual
(Details).
For details on how to set the scaling value, refer to
Small Type Display Unit for Energy Measuring Unit User’s
Manual (Details).
