Timing Chart

|
A
On Delay Power On
|
When the input voltage U is applied, timing delay t begins.
Relay contacts R change state after time delay is complete.
Contacts R return to their shelf state when input voltage U is removed.
Trigger switch is not used in this function.
|
 |
|
B
Repeat Cycle Starting Off
|
When the input voltage U is applied, timing delay t begins. When time delay t is complete, relay contacts R change state for time delay t.
This cycle will repeat until input voltage U is removed. Trigger switch is not used in this function.
|
 |
|
C
Interval Power On
|
When input voltage U is applied, relay contacts R change state Immediately and timing cycle begins. When the time delay is complete, contacts return to shelf state. When input voltage U is removed, contacts will also return to their state. Trigger switch is not used in this function.
|
 |
|
D
Off Delay S Break
|
Input voltage U must be applied continuously. When trigger S is closed, the relay contacts R changes state. When trigger S is opened, delay t begins.
When delay t is complete, contacts R return to their shelf state. If trigger S is closed before time delay t is complete, then time is reset. When trigger S is opened, the delay begins again, and relay contacts remain in their energized state, if input voltage U is removed, relay contacts R return to their shelf state.

E
Retrigger able One Shot
|
Upon application of input voltage U, the relay is ready to accept trigger signal S. upon application of the trigger signal S, the relay contacts R transfer and the preset time t begins. At the end of the preset time t, the relay contacts R return to their normal condition unless the trigger signal S is opened and closed prior to time out t (before preset time elapses). Continuous cycling of the trigger signal S at a rate faster than the present time will cause the relay contacts R to remain closed. If input voltage U is removed, relay contacts R return to their shelf state. |

|
F
Repeat Cycle Starting ON
|
When input voltage U is applied, relay contacts R change state immediately and time delay t begins. When the time t is complete, contacts return to their shelf state for time delay t. This cycle will repeat until input voltage U is removed. Trigger switch is not used in this function.

 |
|
G
Pulse Generator
|
Upon application of input voltage U, a single output pulse of 0.5seconds is delivered to relay offer time delay t. Power must be removed and reapplied to repeat pulse. Trigger switch S is not used in this function.
|
 |
|
H
One Shot
|
Upon application of input voltage U, the relay is ready to accept trigger signal S. Upon application of the trigger signal S, the relay contacts R trasher and the preset time t begins. During time out, the trigger signal S is ignored. The relay resets by applying the trigger signal S when the relay is not energized.

I
On/Off Delay S Make/Break
|
Input voltage U must be applied continuously. When trigger S is closed, time delay t begins. When time delay t is complete, relay contacts R change state and remain transferred until trigger S is opened. If input voltage U is removed, relay contacts R return to their shelf state.
|
 |
|
J
Memory Latch S Make
|
Input voltage U must be applied continuously. Output changes state with every trigger S closure. If input voltage U is removed, relay contacts R return to their shelf state.
