Wiring schemes

Caution : The terminal references enclosed in brackets refer to old version electronic timers.

RE1-LA On-delay

The timer is connected in series between the load which
requires delayed energisation and switch K. The mains
supply can be a.c. or d.c. with any voltage between 24 V
and 240 V. (See page opposite for use of timer in conjunction
with other Telemecanique products).

RE1-LC Off-delay

The timer is connected in series with the load which
requires delayed de-energisation. Switch K is linked to
terminals Y2 and A2 of the timer and terminal A2 is linked
to the mains supply as shown in the scheme opposite. The
unit operates on a.c. current at a voltage between 24 V and
240 V. (See page opposite for use of timer in conjunction
with other Telemecanique products).

Sequential diagrams

RE1-LA On-delay

Mains supply R must be switched on. When switch K
closes, the set timing period t starts and built-in indicator V
lights up simultaneously. When the set time period t has
elapsed, load C is energised and indicator V goes out. Load
C remains energised until switch K opens or until the mains
supply R is switched off.

RE1-LC Off-delay

Mains supply R must be switched on. When switch K
closes, load C is energised. When switch K opens, timing
starts and built-in indicator V lights up simultaneously.
When set time t has elapsed, load C is de-energised and
indicator V goes out. Load C then remains de-energised
until switch K closes again.

Operating principle

On-delay

Timing starts when the relay is energised. When the set time delay (t) has elapsed, the output contact closes. When the
relay is de-energised, the contact returns to its initial position. The output contact does not close if the duration of the
control instruction is less than the set time delay.
Timing can also be started by opening of a control contact (models with external control).

Off-delay

Energisation of the relay or closing of the control contact (models with external control) causes the output relay to close
instantaneously . Timing starts when the relay is de-energised or when the control contact opens. When the set time delay
(t) has elapsed, the contact returns to its initial position. If the energisation time or closing time of the control contact is
less than the minimum time specified, the timing period does not start.

On and Off-delay

This function is a combination of the
On and Off delay functions. The timing
cycle must be controlled by an external
contact.

Timing relay with pulse on energisation

Energisation of the relay causes the output contact to close instantaneously and start the timing period. The contact
returns to its initial position when the set time delay (t) has elapsed or if the supply is cut off before the end of the timing
period.

Timing relay with pulse on de-energisation or on opening of a external control contact

De-energisation of the relay or opening of the external control contact (depending on model) causes the output contact
to close instantaneously and start the timing period. When the set time delay (t) has elapsed, the contact returns to its
initial position.

Flashing relay

Energisation of the relay starts the
flashing period and causes the output
relay to start the flashing cycle. When
the relay is de-energised, the contact
returns to its initial position.

Time delay relays for star-delta starters

Energisation of the relay causes the star contactor to close instantaneously and starts the timing period. When the set
time delay (t) has elapsed, the star contactor returns to its initial position and the delta contactor closes, after a breaking
time sufficient for the changeover.

Multifunction relays

On-delay - Pulse on energisation contact - Symmetrical flasher

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.

Zelio Time timing relays

Solid state output, width 22.5 mm, optimum

General characteristics

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.

RE9-TA

The timing relay is placed in series with the load whose energisation is to be delayed on one side, and switch
K on the other side. The mains supply may be a.c. or d.c. and the voltage may be between 24 V and 240 V.
See function diagram on page opposite.

RE9-RA

The timing relay is placed in series with the load whose de-energisation is to be delayed. Switch K is
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
24 V and 240 V. See function diagram opposite.

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).

General characteristics

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.

(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.

Zelio Time timing relays

Relay output, width 22.5 mm, optimum

General characteristics

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.

These products have a transparent, hinged flap on their front face to prevent any accidental alteration of the settings.
This flap can be directly sealed.

Resistive load

An LC1-F185 contactor supplied with 115 V/50 Hz for a consumption of 55 VA or a current
consumption equal to 0.1 A and cos

ϕ

= 0.3

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.

For cos

ϕ

= 0.3: k = 0.6

The electrical durability therefore becomes:
