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.

supply Description
Active High
Internal • When asserted (condition tied to
DO is true), the circuit provides a
pull-up to 15 V.
• When not asserted (condition tied
to DO is false), the circuit provides
0 V.
External • When asserted (condition tied to
DO is true), the circuit provides a
pull-up to a site-specific voltage,
maximum 30 V.
• When not asserted (condition tied
to DO is false), the circuit provides
0 V.
Active Low
Internal • 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 15 V.
External • 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 a site-specific voltage,
to a maximum of 30 V.
