1.1 Unit Functions and Operation
Features of analog input unit
The analog input unit receives various analog values (i.e., voltage, current, and temperature
values) from laser analog sensors and pressure sensors and converts them internally into
digital values.
•The analog input unit can receive input through a number of channels.
Analog input units: 4 channels
Six types of input ranges can be selected to support a variety of connecting equipment.
•The speed of conversion, such as voltage/current range conversion, is as high as 25
μs/channel (non-isolated).
•Converts input analog values into digital data with up to 16 bits in a resolution range of
1/25,000 to 1/62,500.
