Presentation
A timing relay is a component which is designed to time events in industrial
automation systems by closing or opening contacts before, during or after a set
timing period.
There are two main 'families' of timing relays:
b "DIN rail mounted" relays (RE7, RE8, RE9, RE17, REXL…) designed for
mounting on DIN rails in an enclosure,
b "Panel mounted" relays type RE48A designed for mounting on the front of a panel
to give users easy access to the settings.
These relays have one, two or four outputs. Sometimes the second output can be
either timed or instantaneous.
If the power is switched off during the timing period, the relay reverts to its initial
position.
Application examples:
b opening of automatic doors,
b alarm,
b lighting in toilets,
b car park barriers ...
Defi nitions
The following defi nitions will assist in understanding the operation of these relays:
b Relay output:
This is the most common type of output. When the relay is energized, the moving
armature is attracted by the coil and so actuates the contacts, which change state.
When the relay is de-energized, both the armature and the contacts revert to their
initial position.
This type of output allows complete isolation between the supply and the output.
There are three types of output:
C/O: changeover contact, i.e. when the relay is de-energized, the
circuit between the common point C and N/C is closed and when
the relay is operating (coil energized), it closes the circuit between
the common point C and N/O.
CNC
NO
N/C: a contact that is closed without being actuated is called a
Normally Closed (N/C) contact. NC
N/O: a contact that closes when actuated is called a
Normally Open (N/O) contact. NO
b Solid state output:
These outputs are entirely electronic and involve no moving parts; service life is
therefore increased.
b Breaking capacity:
The current value that a contact is capable of breaking in specifi ed conditions.
b Mechanical durability:
The number of mechanical operating cycles of the contact or contacts.
b Minimum switching capacity (or minimum breaking capacity):
corresponds to the minimum required current which can fl ow through the contacts
of a relay .
b G (Gate) Input:
Gate input allows timing in progress to be interrupted without resetting it.

Function N: Retriggerable interval relay with control signal on
After power-up and an initial control pulse C, the output R closes.
If the interval between two control pulses C is greater than the set timing period T,
timing elapses normally and the output R opens at the end of the timing period. If the
interval is not greater than the set timing period, the output R remains closed until
this condition is met.
Function O: Retriggerable interval delayed relay with control signal on
An initial timing period T begins on energization. At the end of this timing period, the
output R closes.
As soon as there is a control pulse C, the output R reverts to its initial state and
remains in that state until the interval between two control pulses is less than the
value of the set timing period T. Otherwise, the output R closes at the end of the
timing period T.
Function P: Pulse delayed relay with fi xed pulse length
The timing period T starts on energization.
At the end of this period, the output R closes for a fi xed time P.
Function Pt: Pulse delayed relay (summation and fi xed pulse length) with control signal off
On energization, timing period T starts (it can be interrupted by operating control
contact C).
At the end of this period, the output R closes for a fi xed time P.
Function Qc: Star-delta timing
T iming for star delta starter with contact for switching to star connection.
Function Qe: Star-delta timing
On energization, the star contact closes instantly and timing starts.
At the end of the timing period, the star contact opens.
After a 80 ms pause, the delta contact closes and remains in this position.
