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.

DO Fault Action
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 .
