Analogue output modules
5.10.1 PCD2.W4x0, analogue outputs, 4 channels, 8 bit resolution
Application
High-speed output module with 4 output channels of 8 bits each. Different output
signals can be chosen with the aid of jumpers. Suitable for processes in which a
large number of actuators have to be controlled, such as in the chemical industry and
building automation.
