5.4.5 PCD3.W4x0, analogue outputs, 4 channels, 8 bit resolution
Application
Fast output module with 4 output channels of 8 bits respectively. Different output
signals can be chosen with the aid of jumpers. Suited for processes in which a large
number of actuators must be controlled such as in the chemical industry and building
automation.
