Options for Discrete Output PolarityTable 6-5:
Polarity Description
Active High • When asserted (condition tied to DO is true), the cir-
cuit draws as much current as it can, up to a maximum
of 10 mA.
• When not asserted (condition tied to DO is false), the
circuit draws less than 1 mA.
Active Low • When asserted (condition tied to DO is true), the cir-
cuit draws less than 1 mA.
• When not asserted (condition tied to DO is false), the
circuit draws as much current as it can, up to a maxi-
mum of 10 mA.

Overview
Discrete Output Fault Action controls the behavior of the discrete output if the transmitter
encounters an internal fault condition.
Note
For some faults only: If Fault Timeout is set to a non-zero value, the transmitter will not implement the
fault action until the timeout has elapsed.
CAUTION!
Do not use Discrete Output Fault Action as a fault indicator. If you do, you may not be able to
distinguish a fault condition from a normal operating condition. If you want to use the discrete
output as a fault indicator, set Discrete Output Source to Fault and set Discrete Output Fault Action to
None.
Procedure
Set Discrete Output Fault Action as desired.
The default setting is None.
