Analogue input and output modules
5.12.1 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.
