Input/output (I/O) modules

5

5.12.1 PCD2.W6x5, analogue outputs, 6 (4) channels, 10 bit resolution, el. isol.

Application

High-speed output module with galvanic separation of outputs to PCD bus, for

general use with 6 (4) channels, each with 10 bit resolution. Different variants for

voltage 0 ... 10 V, -10 V ... +10 V and current 0 ... 20 mA are available.

Module overview Channels Resolution
