Does Schneider Electric offer a 'true off delay' (self powered off delay) timer?

For an off delay timer to work correctly it is necessary to either; connect a permanent power supply to the timer*, or design the timer such that it can be self powered for the maximum 'off delay' time selectable (the self power energy is usually stored in a small capacitor within the product).

Schneider Electric have both types of delay on de-energisation timers in the Zelio Time DIN rail mounted electronic timer offer.

The self powered, 'true off delay' timer (described as 'without auxiliary supply' in the catalogue) is the RE7RB13MW. This timer has a maximum off delay of 10 minutes.

Important note concerning use of RE7RB13MW : In order to charge the capacitor in the timer there are two operational conditions that must be observed;

  • If the device has been stored or unused, de-activated, for more than a month, it must be energised (by the control circuit) for at least 15 seconds in order to active it.
  • Subsequent operations require the control circuit to be applied for at least 1 second in order for correct operation on removal of control supply.
Failure to observe these precautions will result in the timer output remaining energised indefinitely.

*The timers that utilise a permanent power require the use of a 'control contact' (external control contact) wired according to our technical literature.
