Table 3 – Performance specifications
Specify Run/Stop of the channel to execute A/D conversion.
If the unused channel is set to Stop, the Run time can be
reduced.
Specify analog input range to be used.
Four input ranges are available for voltage input module while
two input ranges are available for current input module.
Specify digital output type.
Four output data formats are provided in this module.
Sampling processing: This is performed if A/D conversion type
is not specified.
Filter processing: This is to introduce delay when there is a
noise or sudden change of input value.
Average processing: Average A/D conversion value based on
frequency or time output.
The user program detects if an analog input with the range of 1
~ 5V (4 ~ 20mA) is disconnected.
