Module Features Chapter 3
The module may operate with values beyond the 4 mA…20 mA range. If an input
signal beyond the low and high signals is present at the module, such as 3 mA,
that data is represented in terms of the engineering units set during scaling.
Table 4 shows example values that may appear based the example mentioned
previously.
