This table assumes that Discrete Output Polarity is set to Active High. If Discrete Output Polarity is set to Active
Low, reverse the voltage values.

Overview
Discrete outputs have two states: ON (active) and OFF (inactive). Two different voltage
levels are used to represent these states. Discrete Output Polarity controls which voltage level
represents which state.
Procedure
Set Discrete Output Polarity as desired.
The default setting is Active High.

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.
