Analog input module SM 331; AI 8 x 12 bit;(6ES7331-7KF02-0AB0)

6.7.1 Analog input module SM 331; AI 8 x 12 bit;(6ES7331-7KF02-0AB0)
Order number
6ES7331-7KF02-0AB0
Properties
● 8 inputs in 4 channel groups
● Programmable measurement type at each channel group
– Voltage
– Current
– Resistance
– Temperature
● Programmable resolution at each channel group (9/12/14 bits + sign)
● Any measuring range selection per channel group
● Programmable diagnostics and diagnostic interrupt
● Programmable limit value monitoring for 2 channels
● Programmable hardware interrupt when limit is exceeded
● Electrically isolated to CPU and load voltage (not for 2-wire transducers)
Resolution
The resolution of measured values is directly dependent of the selected integration time. In
other words, the longer the integration time for an analog input channel, the higher the
resolution of a measured value.
Diagnostics
For information on diagnostics messages at the "group diagnostics" parameter, refer to
chapter Diagnostic messages of analog input modules
Hardware interrupts
Hardware interrupts for channel groups 0 and 1 can be programmed in
set a hardware interrupt only for the first channel of a channel group, that is, either at
channel 0, or at channel 2
