Analog power supply
These Modules convert 12-bit binary data to voltage or current output. Each
Module has a different type of output. Outputs can be either unipolar or bipo-
lar, with the resolution depending on the model.
Output ranges: 0 to 10 V, 0 to 5 V, or 1 to 5 V (4 to 20 mA)
Data format: 12-bit binary
Data conversion for unipolar outputs is illustrated below.
