Analog input 1746-NI4
Posted 03 December 2004 - 11:07 AM
I used AB 1746-NI4 analog module to read the 4-20ma from Zener AC Drive. I have correct measured signal (regulated from 4 to 20ma) but why the reads data on SLC always 32767? event signal is 4 mA? How to solve this problem?

(0-20mA range translates to 0-32767 counts, when using only 4-20mA range, reading is something like 6553-32767).

Scaling example, the following scales an input from a NI4 for 0-100%,
