Timing Diagrams for Predefined Timer Operating Modes

NOTE: Input A is shown as a Sourcing input (active high). If a Sinking input (active low) is used, the logic levels for Input A would be inverted.
On-Delay Timing
Input A
Output 1
Off-Delay Timing
Input A
T
Output 1
The input signal must be wired to both the Input A and
User Input 1 terminals. The Timer Input plug jumper and
the User Input plug jumper must both be set to the
same position (either both SNK or both SRC).
Repeat Cycle Timing

On-Delay / Interval Timing

Input A
Output 1

Interval Timing (Level triggered)

Input A
Output 1
The input signal must be wired to both the Input A and
User Input 1 terminals. The Timer Input plug jumper and
the User Input plug jumper must be set to opposite
positions (one SNK, one SRC) and the Input signal must
be a current sinking type (i.e. pulls input to common).
