MPR-63
In device
,
this feature gives the possiblity that observing the measured values by
other devices with converting these values in to 0-10 V or 2-10 V voltage data.
The below parameters can be set as analog output in device

For example
Below settings should be fulfilled as like :
Type
Type
: 2-10 V
Prm (Parameter) : I
L1
Lo(Low value)
: 100 mA
Hi (High value)
: 5 A
After above settings are completed;
Analog voltage output’s value will be 2 V when I
L1
value is 100mA,
Analog voltage output’s value will be 10 V when I
L1
value is 5 A.
When I
L1
is 3.5 A analog voltage output value will be;
I
out
= (10-2)x(3.5-0)
(5-0.1)
+ 2 = 7.714 V
(10-0)x[400-(-250)]
[750-(-250)]
= 6,5 V
For example
Below settings should be fulfilled as like :
Type
Type
: 0-10 V
Prm (Parameter) :

Q
Lo(Low value)
: -250 VAr
Hi (High value)
: 750 VAr
After above settings are completed;
Analog voltage output’s value will be 0 V when
Σ
Q value is -250 VAr,
Analog voltage output’s value will be 10 V when
Σ
Q value is 750 VAr.
When
Σ
Q is 400 VAr analog voltage output value will be;
