Option - Adder Subtractor, Min/Max Select SI139
Input Option 61:
Iout=I 1I 2 OR IOUT =
Adder
I 1I 2
(AVERAGER)
2
Input loads (4-20mA) :
I1 =50 , I 2=50 0.7V
Input Option 62:
Subtractor
IOUT =I1 −I 2
Input loads (4-20mA) :
I1 =50 , I 2=50 0.7V
Input Option 64:
Minimum Selector
The output signal will follow the lower of both input signals.
Input load: 56Ω (4-20mA)
Input Option 65:
Maximum Selector
The output signal will follow the higher of both input signals.
Input load: 56Ω (4-20mA)
Input Option 68: Adder,
I OUT =I 1I 2 (ADDER)
I OUT =
69: Subtractor
I OUT =I 1−I 2
I 1I 2
(AVERAGER)
2
Unlike options 61 and 62 the two inputs can be any current or voltage
signal, however they must be independently sourced or have a
common 0V.
Must specify Calibration for each input when ordering e.g.
In1 Cal:
1-5V
In2 Cal:
0-20mA.
