5.11.2 PCD2.W6x0, analogue outputs, 4 channels, 12 bit resolution

Application

High-speed output module for general use with 4 channels, each with 12 bit

resolution. Different variants for voltage 0 ... 10 V, -10 ... +10 V and current 0 ... 20 mA

are available.

External current consumption: max. 100 mA (type PCD2.W610 only, for current

outputs)

Terminals: Pluggable 10-pole screw terminal block

(4 405 4847 0), for wires up to 1.5 mm²

*) Note on current outputs:

Since for some applications it is important to be able to reach the outside limit

values of the range (0 mA, 20 mA), current outputs have been laid out according to

the following characteristic line:

During the start, a voltage of 5 V will be at all outputs of the module PCD2.W600.

The starting phase lasts 40 ms, afterwards 0 V will be put to the outputs.
