Input/output (I/O) modules

5

5.9.1 PCD2.W5x0, analogue inputs/outputs, 2 + 2 channels, 12 bit resolution

Application

Combined high speed analogue input/output module with 2 voltage inputs and 2

voltage outputs 0 ... +10 V (unipolar) or -10 ... +10 V (bipolar), jumper selectable, all

with 12 bit resolution. The module is suitable for precise, high-speed applications.
