AI204/x
The analog input module AI204/x offers two or
four high-resolution 16 bit analog input channels
depending on the model. The extraordinarily high
accuracy with integrated temperature calibration
predestine this unit for demanding measurement
applications for industrial processes.
•1, 2, or 4 analog inputs
•Input voltage -10 to +10 V
•Resolution: 16 bit
•Sample time from 20 µs
•Inputs can be synchronized
•Galvanic isolation of channels
•Galvanic isolation from system
•Temperature calibration
•Connection possibility differential
•Internal voltage generation is monitored
