Function

Operation

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 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, relay contacts R change 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

Retriggerable 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 preset 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 time delay 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 0.5 seconds 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 thrasher and the preset time↑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 shelfsate.
