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

On-Delay / Interval Timing

Input A			Input A
	T	T		T1	T2	T
Output 1			Output 1

Off-Delay Timing

Input A

T T

Output 1

Interval Timing (Level triggered)

Input A

T 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).

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).

Repeat Cycle Timing

Input A
T1	T2	T1	T
Output 1

Interval Timing (Edge triggered)
