3.5.14 Voltage/Current Output

The module has one 8-channel DAC and 8 programmable output drivers. They
are configured and set based on user-configurable parameters.
The final current or voltage output signal is determined by:
• Range
• Data Format
• Output Word
• Operational state of the module:
-
Run
-
Program
- Fault
Regardless of the final scaled value, the output is clipped to a High and Low
Limit based on the following table:
• The High and Low Range values indicate the intended use of the Range.
• The Current Ranges allow for a 2% overhead at each Range endpoint.
• The Voltage Ranges allow for a 5% overhead at each Range endpoint.
• Ranges with a 0 mA or 0 V Low Range are clipped at 0 mA or 0 V and
do not go negative.
