Options for Discrete Output PolarityTable 6-9:
Polarity Description
Active High
• 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.
Active Low
• 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.
