Note For bipolar outputs, bit 11 is OFF for positive output values and ON for negative
output values.
The Analog Output Unit converts digital output data to analog signals. It converts
the 12-bit binary data output by the CPU Unit program to either an voltage or
current output. Five models are available to support different output ranges.
The analog output signals can be unipolar outputs which are positive, or bipolar
outputs which are positive and negative. The resolution differs according to the
output range.
Output Ranges: 1 to 5 V
4 to 20 mA
0 to 10 V
0 to 5 V
