Control Relays and Timers
Ti m i n g Rel ay s
Function #7—Universal TR
Pulse Sequence Monitoring
When the supply voltage U
is applied, the set interval t1
begins and the output relay
R switches to the ON
position. After the interval
t1 has expired, the interval
t2 begins. As long as the
control switch S is closed
and opened within the
interval t2, the relay will
remain in the ON position.
If the control switch is not
closed and opened within
the interval t2, the relay
will change to the OFF
position until supply
voltage U is interrupted
and reapplied.
Function #8—Universal TR, TRN, TMR5, TMRP
ON Delay, Power Triggered
Delay ON Make
When the supply voltage U
is applied, the set interval t
begins. After the interval t
has expired, the output relay
R switches to the ON
position. The relay will remain
in that position until supply
voltage U is interrupted.
Function #9—Universal TR, TRN, TMR5, TMRP
Single Shot Leading Edge Voltage Controlled
Interval ON/Interval (Power Start)
When the supply voltage U
is applied, the output relay R
switches to the ON position
and set interval t begins.
After the interval t has
expired, the output relay R
switches to the OFF position.
The relay will remain in that
position until supply voltage U
is interrupted. If the supply
voltage is interrupted prior to
interval t timing out, the relay
will immediately switch to the
OFF position.

Function #10—Universal TR, TRF, TMR5, TMRP, E5-248
OFF Delay/Signal OFF Delay
Delay ON Release
The supply voltage U must
be constantly applied to the
device. When the control
contact S is closed, the
output relay R switches to
the ON position. When the
control contact is opened,
interval t begins. After the
interval t has expired, the
output relay R switches
to the OFF position. If the
control contact S is closed
before interval t expires,
the output relay will remain
in the ON position until the
control switch opens, at
which time the interval t
will begin again.
Function #11—Universal TR, TRF, TMR5, TMRP, E5-248
Single Shot Leading Edge with Control Input
Single Shot/One Shot (Signal Start)/Momentary Interval
The supply voltage U must
be constantly applied to the
device. When the control
contact S is closed, the
output relay R switches to
the ON position and the set
interval t begins. After the
interval t has expired, the
output relay R switches to
the OFF position. The control
contact is ignored during the
interval t, and a new cycle
cannot be started until the
set interval t has timed out.
Function #12—Universal TR
Single Shot Trailing Edge with Control Input
The supply voltage U must
be constantly applied to the
device. When the control
contact S is closed and
reopened, the output relay
R switches to the ON
position and the set interval t
begins. After the interval t
has expired, the output
relay R switches to the
OFF position. The control
contact is ignored during
the interval t, and a new
cycle must be started
after the set interval t has
timed out.
