1771-NIV Module The 1771-NIV module is an 8-channel high resolution (16-bit) analog
voltage input module. Each channel has a range of -5 to 5V dc.
Module Configuration
When you add a 1771-NIV module to a rack, the 1771-NIV Module
dialog box opens.
To configure the 1771-NIV module, complete the following steps.
1. For each channel, enter the scaling values.
The low scaling value corresponds to the minimum input
voltage; the high scaling value corresponds to the maximum
input voltage. For example, if the scaling values are 10.0 and
22.5, an input voltage of -5V dc produces a value of 10.0 and an
input voltage of 5V dc produces a value of 22.5. The range of
scaling values is -3.4e38 to 3.4e38.
