YX531T Guide Rail Type Multifunctional Time Relay

A. Power-On Delay Mode
When input voltage U is applied, the set delay time t starts. After the delay, the relay contacts R engage and remain engaged until power is cut off, at which point the relay contacts R reset.

B. Cycle Mode 1
When input voltage U is applied, the set delay time t starts. After the delay, the relay contacts R engage, then the delay t is repeated, the relay contacts R release, and this process repeats.

C. Power-Off Delay Mode
When input voltage U is applied, the relay contacts R engage, and the set delay time t starts. After the delay, the relay contacts R reset.

D. Trigger Mode 1
When input voltage U is applied, the relay contacts R engage when the trigger switch S is closed. When S is opened, the delay t starts. After the delay, the relay contacts R release and reset. If S is closed again before the delay t is completed, the delay setting t will reset.

E. Trigger Mode 2
When input voltage U is applied and the trigger switch S is closed, the relay contacts R engage, and the delay t starts. Regardless of whether S opens or closes, when the delay t is completed, the relay contacts R release. If S is closed again before the delay t is completed, the delay setting t will reset.

F. Cycle Mode 2
When input voltage U is applied, the relay contacts R engage, and the delay t starts. After the delay, the relay contacts R release, the delay t is restarted, and after completion, the relay contacts R engage again. This process repeats.

G. Pulse Generator
When input voltage U is applied, the delay t starts. After the delay, a 0.5-second pulse signal is output to the relay.

H. Trigger Mode 3
When input voltage U is applied and the trigger switch S is closed, the relay contacts R engage, and the delay t starts. Regardless of whether S opens, after the delay is completed, the relay contacts R release. The difference from mode E is that during the delay, additional trigger signals from the switch S are ignored, and the delay setting does not reset.

I. Trigger Mode 4
When input voltage U is applied and the trigger switch S is closed, the delay t starts. After the delay is completed, the relay contacts R engage. When the trigger switch S is opened, the delay t is restarted, and after the delay, the relay contacts R release.

J. Step Mode
When input voltage U is applied, each activation of the trigger switch S changes the state of the relay contacts R accordingly, and the delay t does not apply to this process.
