Functions and selection
Functions
Diagram Operating principle
On-delay
Control or
Timing starts when the relay is energised. When the set time delay (t) has elapsed, the output contact closes. When the
supply
relay is de-energised, the contact returns to its initial position. The output contact does not close if the duration of the
C/O contact
control instruction is less than the set time delay.
t
Timing can also be started by opening of a control contact (models with external control).
Off-delay
Control or
Energisation of the relay or closing of the control contact (models with external control) causes the output relay to close
supply
instantaneously . Timing starts when the relay is de-energised or when the control contact opens. When the set time delay
C/O contact
(t) has elapsed, the contact returns to its initial position. If the energisation time or closing time of the control contact is
t
less than the minimum time specified, the timing period does not start.

Additional functions
External control of starting: opening of an external contact connected to the relay starts the timing period. Closing of this contact resets the timer.
External control of partial stop of time delay: closing of an external contact connected to the relay allows the timing period to be interrupted. The time
elapsed is memorised. Timing restarts as soon as the contact opens. This type of control enables the totalising function to be performed.
External adjustment of the time delay: one or more external potentiometers can be used for remote adjustment of the timing period or periods.

Presentation
The RE9 range of relays is designed for simple, repetitive applications with short and intensive cycles because their solid
state output provides very high electrical durability.
Each product has a single timing range.
Each relay has a wide voltage range from 24 to 240 V.
The range comprises 9 references with 3 model types:
- RE9-TA: On-delay,
- RE9-RA: Off-delay,
- RE9-MS: multifunction.
These products have a transparent, hinged flap on their front face to avoid any accidental alteration of the setting.
This flap can be directly sealed.

Load
The timing relay is placed in series with the load whose de-energisation is to be delayed. Switch K is
A1 L
connected to terminals Y2 and A2 of the timing relay, and terminal A2 is connected to the mains supply as
indicated in the scheme opposite. The device is operated from an a.c. mains supply whose voltage is between
Y2 A2
K
24 V and 240 V. See function diagram opposite.
Supply c
Note: For supply voltages greater than 30 V, the rated voltage of the load is equal to the supply voltage. For a supply voltage of 24 V, the voltage drop within the
RE9 relay must be taken into account (about 3 V); a coil with a nominal voltage of 21 V must therefore be selected for the load (see page 28468/3).

Presentation
The RE7 range of relays, with only 23 references, covers all timing applications.
These relays offer multi-range timing from 50 ms to 300 h.
They are multi-voltage.
Three models combine several different functions: multifunction relays.
These products have a transparent, hinged flap on their front face to avoid any
accidental alteration of the settings. This flap can be directly sealed.

For 0.1 A, curve 1 indicates a durability of approximately 1.5 million operating cycles.
As the load is inductive, it is necessary to apply a reduction coefficient k to this number of
cycles, as indicated by curve 2.

(1) If the device has been stored, de-energised, for more than a month, it must be energised for about 15 seconds to
activate it. Subsequently, a time of > 1 s is enough to activate the time delay.
If this time is not complied with, the relay will remain energised indefinitely.
(2) By external potentiometer, to be ordered separately. If external potentiometer is fitted, the internal potentiometer is
automatically disconnected.
(3) A switch on the front face of the relay allows the second changeover contact to be used in instantaneous mode.

Presentation
The RE8 range of relays is designed for simple and repetitive applications, providing basic functions.
Each relay comprises:
- a single timing range,
- a C/O output relay.

(1) For easier adjustment, it is preferable to set the time delay between the maximum value in the range and one tenth
of this value.
Example: RE8-PE11BUTQ timing range 0.1 s& 10 s, recommended use 1 s& 10 s.
(2) Correct operation of the star-delta starter is only possible if the wiring scheme on page 28463/3 is strictly complied
with.

Setting-up
1 Potentiometer for fine adjustment of the time delay, graduated in % of range max. setting 2.
2 Marking of maximum time delay value.
1
3 3 LEDs, depending on the models :
2
- Yellow LED: illuminates when the output relay is energised,
- Green LED: illuminates when the RE8 is energised.
Adjustment of the time delay
- The maximum value of the timing range is printed on the product 2.
1 24
Example: RE8-PE11BUTQ; maximum time delay: 10 s.
- Time required 2.4 s; using potentiometer 1 set the value of the time delay required as a % of value 2:
2 10 s x. %
t x 100 2.4 x 100
value 1 =       =         = 24
