Product description

Operation mode: Lagged deactivation.
Timing relays are devised to time the control of industrial and domestic automatic control engineering systems (e.g. ventilation, heating, lighting, signalling, etc.).

Until the relay is activated, the contact remains in the 11-10 position. After the power voltage is supplied, contact is shifted to position 11-12 and the countdown of the preset value t is commenced. After the preset time t has been counted down, contact returns to position 11-10. The working sequence of the relay may be repeated after turning the power supply off and on.


* Setting the time range knob regulator in the:
  ON - position with power supply activated results in the permanent closure of the contact in position 11-12.
  OFF - position (power supply activated) causes the contact to be permanently closed in the 11-10 position.
* With the power supply on, the system does not respond to time range setting modifications.
* The newly set time range is active after the power supply has been turned off and on.
* With the power supply on, it is possible to regulate the preset time freely within the selected time range.
