Control Relays and Timers
Ti m i ng Relay s
Product Overview
Timer Function Descriptions
Function #1—Universal TR, TMR5, E5-248
Asymmetrical Flasher, Pause First
Repeat Cycle, OFF/ON Delay
When the supply voltage U
is applied, the set interval t1
begins. After the interval t1
has expired, the output relay
R switches into ON position
and the set interval t2 begins.
After the interval t2 has
expired, the output relay
switches into OFF position.
The output relay is triggered
at the ratio of t1:t2 until the
supply voltage is interrupted.
Function #2—Universal TR, TMR5, E5-248
Asymmetrical Flasher, Pulse First
Repeat Cycle, ON/OFF Delay
When the supply voltage U
is applied, the output relay R
switches into the ON position
and the set interval t1 begins.
After the interval t1 has
expired, the output relay R
switches into OFF position
and the set interval t2 begins.
After the interval t2 has
expired, the output relay
switches into ON position.
The output relay is triggered
at the ratio of t1:t2 until the
supply voltage is interrupted.
Function #3—Universal TR
ON Delay and OFF Delay with Control Contact
The supply voltage U must
be constantly applied to the
device. When the control
contact S is closed, the set
interval t1 begins. After the
interval t1 has expired, the
output relay R switches into
ON position. If the control
contact is opened, the set
interval t2 begins. After the
interval t2 has expired, the
output relay R switches into
OFF position. If the control
contact is opened before the
interval t1 has expired, the
interval already expired is
erased and is restarted with
the next cycle.

Function #4—Universal TR
ON Delay and Single Shot Leading Edge Voltage Controlled
When the supply voltage U
is applied, the set interval t1
begins. After the interval t1
has expired, the output relay
R switches into ON position
and the set interval t2 begins.
After the interval t2 has
expired, the output relay
switches into OFF position. If
the supply voltage is
interrupted before the interval
t1 + t2 has expired, the
interval already expired is
erased and is restarted
when the supply voltage is
next applied.
Function #5—Universal TR
ON Delay and Single Shot Leading Edge Control Contact
The supply voltage U must
be constantly applied to the
device. When the control
contact S is closed, the set
interval t1 begins. After the
interval t1 has expired, the
output relay R switches into
ON position and the set
interval t2 begins. After the
interval t2 has expired, the
output relay R switches into
OFF position. During the
interval, the control contact is
ignored. A new cycle can only
be initiated when the cycle
has been completed.
Function #6—Universal TR
Single Shot Leading and Single Shot Trailing Edge
with Control Contact
Asymmetrical Signal ON/OFF Delay
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 t1 begins. After the
interval t1 has expired, the
output relay R switches into
OFF position. If the control
contact S is opened, the
output relay again switches to
the ON position and the set
interval t2 begins. After the
interval t2 has expired, the
output relay R switches into
OFF position. During
the interval, the control
contact is ignored. During
the interval, the control
contact can be operated
any number of times.
