Analog Input Modules
31007715 6/2008 145
In the 0 to 20 mA operating range, linear current representations can be
interpreted using the formula, where V
n
is the numerical count and I
ai
is the analog
input current:
Here is an example in signed input data format:
V
n
= I
ai
x 1 600 (I
ai
in mA) for the signed input data format
V
n
= I
ai
x 3 200 (I
ai
in mA) for the unsigned input data format
