1762IF4 not reading the full range

jmason · Sep 11, 2018

Having an issue with An AB 1762-IF4 .
I am trying to read a 0-10 VDC signal but only seeing counts up to 37762
I have checked the input voltages and they are reading correct with a DVM.

the system is a load cell set up for 0-10vdc
0-5 VDC = 0 -5000 and 5-10vdc 0 +5000.
Any assistance would be great.
Thank you
Jay

Question
1762-IF4 or 1762IF4 Analog Input Data Format.
Answer
Raw/Proportional
Data Table Value Voltage/Current Value
32767 10.5 Volts
31206 10 Volts
0 0
-31206 -10 Volts
-32767 -10.5 Volts
32767 21 mA
31206 20 mA
6241 4 mA
0 0 mA
Scaled for PID
Data Table Value Voltage/Current Value
16793 10.5 Volts
16383 10 Volts
8192 0
0 -10 Volts
-410 Less than -10 Volts
17407 21 mA
16383 20 mA
0 4 mA
-819 Less than 4 mA

but only seeing counts up to 37762

Really??

See above for raw data values
