Properties
● Two inputs in one channel group
● Programmable measurement type for 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 one channel
● Programmable hardware interrupt when limit is exceeded
● Electrically isolated from the CPU and load voltage (not for 2DMU)
Resolution
The measured value resolution is directly proportional to the selected integration time, that
is, the measured value resolution increases in proportion to length of the integration time at
the analog input channel.
Diagnostics
For information on diagnostics messages at the "group diagnostics" parameter, refer to
chapter Diagnostic messages of analog input modules.
