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.

Description
• When asserted (condition tied to DO is
true), the circuit provides a pull-up to 24 V.
• When not asserted (condition tied to DO is
false), the circuit provides 0 V.
• When asserted (condition tied to DO is
true), the circuit provides 0 V.
• When not asserted (condition tied to DO is
false), the circuit provides a pull-up to 24 V.
