Timing relay, on- and off-delayed with and without random switching
Time value I1: on-delay time
Time value I2: off-delay time
Random switching
The contact of the timing relay switches randomly within the setpoint value
ranges.

• Range A: The relay processes the two times without any interruption.
• Range B: The trigger coil drops out before the on-delay is reached.
• Range C: The stop coil stops the timeout of the on-delay.
• Range D: The stop coil has no effect in this range.

• Range E: The stop coil stops the timeout of the off-delay.
• Range F: The reset coil resets the relay after the on delay has elapsed
• Range G: After the reset coil is activated, the internal time counter is reset.
The switching contact remains switched off. The function relay waits for a new trigger pulse.
