CAUTION Do not assign two input microblocks to the same physical input using Dry Contact in one and
Binary Input in the other. This results in faulty behavior. 5
1 The sensor reads a value and sends a corresponding signal (Volt or mA) to the TV-MPCXP1628-NR's physical
input. The Analog Input microblock uses the Min and Max values to linearly translate the signal into the
engineering value used in subsequent control logic. For example, set Min to 0 and Max to 10 for a 4
– 20 mA
sensor that measures velocity from 0.0 to 10.0 inches/second so that when the input reads 4 mA, the
microblock outputs a value of 0. Similarly, when the input reads 8 mA, the microblock outputs a value of 2.5.
2 You can set up a custom translation table on the driver's Custom Translation Tables pages in the i-Vu®
interface.
3 The control program must have one Pulse to Analog Input microblock for each pulse counting input.
4 To improve the accuracy for RTD sensors used with long cables, see Offset/Polarity values (page 43).
5 Binary Input and Dry Contact input types are not interchangeable. Setting an input to Dry Contact applies a
wetting voltage to sense a dry contact. Setting an input to Binary Input will not apply a wetting voltage.
