Electronic timers Selection guide Applications Electronic timers enable simple automation cycles to be set up using wired logic. They can also be used to complement the functions of PLCs. Timers with solid state output reduce the amount of wiring required (wired in series). The durability of these timers is independent of the number of operating cycles. 2 Enclosure type Modular 17.5 mm DIN, width 22.5 mm Timing range Number of ranges 112 Extreme values Depending on model: Depending on model: 0.1…10 s 0.1…3 s 0.1…10 s 3…300 s 1…30 s 0.3…30 s 10…300 s 3…300 s 2…60 min 40 s…60 min Output circuit Control circuit voltage, depending a 24…240 V a 24…240 V on model c 24…240 V c 24…240 V Type RE1 RE9 2/5 2/8 and 2/9 Pages 2/2 Te Relay outputs provide complete isolation between the supply circuit and the output.

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 2 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 supply 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 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. On and Off-delay Symmetrical Control or supply This function is a combination of the The On and Off delays are equal. On and Off delay functions. The timing C/O contact cycle must be controlled by an external Asymmetrical ta tr contact. The On and Off delays are adjusted by 2 different potentiometers. Timing relay with pulse on energisation Supply 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 C/O contact period. t Timing relay with pulse on de-energisation or on opening of a external control contact Control or supply 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 C/O contact initial position. t Flashing relay Symmetrical flashing relay Supply Energisation of the relay starts the The On and Off flashing phases are identical. flashing period and causes the output C/O contact relay to start the flashing cycle. When Asymmetrical flashing relay ta tr the relay is de-energised, the contact The On and Off flashing phases are adjusted by 2 different potentiometers returns to its initial position. (ta and tr). Time delay relays for star-delta starters Supply 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 Star time sufficient for the changeover. Delta t t3 Multifunction relays On-delay - Pulse on energisation contact - Symmetrical flasher Same functions as above + Off-delay - Pulse on energisation contact with externally controlled start - Symmetrical flasher Same functions as above + Star Delta starting (External control of start of the timing period is not possible for the star delta starting function). 2/8 Te 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.
