Timing relay, off-delayed with and without random switching
Random switching, with and without retriggering
The contact of the timing relay switches randomly within the setpoint value
range.
Retriggering
When the time is running and the trigger coil is reactivated or deactivated,
the actual value is reset to zero. The set time of the timing relay is timed out
once more.

t
s
: Setpoint time.
• Range A: The time elapses after the trigger coil is deactivated.
• Range B: The Stop coil stops the time from elapsing.
• Range C: The reset coil resets the relay and the contact.
After the reset coil drops out, the relay continues to work normally.
• Range D: The Reset coil resets the relay and the contact when the function block is timing out.

(with/without random switching, with/without retriggering)
• Range E: The trigger coil drops out twice.
The set time t
s
consists of t
1
plus t
2
(switch function not retriggerable).
• Range F: The trigger coil drops out twice.
The actual time t
1
is cleared and the set time t
s
elapses completely (retriggerable switch function).
