Outline and dimensions of wiring diagram (mm)
A: Power on delay
When relay Un is powered on, the relay begins to delay, and after a delay of t, the output contacts close. relay
After the power is cut off, the output contact is disconnected, and the S control signal is invalid in this functional mode.
B: off delay
When the relay Un is powered on, the output contact of the relay immediately closes, causing a delay. After a delay of t, the output is delayed
If the contact is disconnected, and the delay time t has not reached the point where the relay Un loses power, the output contact will be disconnected, and S will control it
The signal is invalid in this functional mode.
C: Loop delay (starting from OFF)
When relay Un is powered on, the relay begins to delay, and after a delay of t, the output contacts close. At the same time
After a delay time t, the relay output contact opens, and this cycle continues until the relay Un
Power loss, the S control signal is invalid in this functional mode.
D: Loop delay (ON start)
When the relay Un is powered on, it closes and begins to delay. After a delay of t, the output contact opens
After a delay time t, the relay output contact closes, and this cycle continues until the relay is delayed
Un loses power, S control signal is invalid in this functional mode.
E: Delay disconnection (starting from triggering the falling edge of S)
When the relay Un is in the powered state, when the S control terminal is turned on, the relay closes and the S control terminal
When disconnected, the relay starts to delay, and after a delay of t, the output contact opens. During the delay of t, the S control terminal
Reconnect, reset delay t to zero, and then delay again.
F: Delay disconnection (starting from S rising edge triggering)
When the relay Un is in the powered state, when the S control terminal is turned on, the relay closes, and at the same time, the relay
Start delay, after delay t, the output contact will disconnect, and during the delay t process, the S control terminal will reconnect. Delay t will protect
Continue to delay without change.
G: S falling edge triggers closure, delayed disconnection
When the relay Un is in the powered state and the S control terminal is disconnected, the relay closes, and at the same time, the relay
Start the delay, and after a delay of t, the output contact will disconnect. During the delay of t, the S control terminal will reconnect and disconnect, causing a delay
Keep t unchanged and continue to delay.
H: Connection and disconnection delay
When the relay Un is in the powered state and the S control terminal is turned on, the relay starts to delay. After a delay of t
The output contact is closed, and when the S control terminal is disconnected, the relay starts to delay. After a delay of t, the output contact opens.
I: Pulse conversion
When the relay Un is in the powered state and the S control terminal is connected, the relay output contact state transitions.
J: pulse output
After the relay Un is powered on, the relay starts to delay. After the delay time t, the output contact of the relay closes for 0.5s
Later disconnect.
