If an expansion module's analog input is receiving current or voltage in excess of the absolute maximum rating, the corresponding Out Of Range indicator lights up.
IO-AI4-AO2
Analog value: from 0 to 4095 (12 bit). If the analog input is:
below 0V/0mA, then the analog value will be 0.
above 10V/20mA (about 2% above the full scale), then the analog value will be 4096.
IO-ATC8
Analog value: from 0 to 16383 (14 bit). If the analog input is:
slightly below 0V/0mA (about 0.5% below 0V/0mA), then the analog value will be -1.
slightly above 10V/20mA (about 0.5% above the full scale), then the analog value will be 16384.
If the analog input is greatly below or above of the analog input range ,but still within the range of the absolute maximum rating, then the analog value will be 32767.
V120-12-R1, V120-12-R2C, V200-18-E1, V200-18-E1B and V200-18-E2B
Analog value: from 0 to 1023 (10 bit). If the analog input is:
Below 0V/0mA, then the analog value will be 0.
Above 10V/20mA (about 2% above the full scale), then the analog value will be 1024.
V120-12-UN2, V120-12-UA2
Analog value: from 0 to 16383 (14 bit). If the analog input is:
Slightly below 0V/0mA (about 0.5% below 0V/0mA), then the analog value will be -1.
Slightly above 10V/20mA (about 0.5% above the full scale), then the analog value will be 16384.
Greatly below or above of the analog input range, but still in the range of the absolute maximum rating, then the analog value will be 32767.
Note that the absolute maximum rating of the analog inputs for all the units is +/- 15V.
