Product description

Timing relays are devised to time the control of industrial and domestic automatic control engineering systems (e.g. ventilation, heating, lighting, signalling, etc.).
With external time setting knob.

Functioning

Working  mode:
LAGGED  DEACTIVATION(A)
Until the relay is activated, the contact remains in the 10-11 position. After the power voltage is supplied (green LED U is shining), contact is shifted to position 10-12 and the countdown of the preset value „t” is commenced (red LED is shining). After the preset time „t” has been counted down, contact returns to position 10-11. The working sequence of the relay may be repeated after turning the power supply off and on.
LAGGED ACTIVATION (B)
After the power voltage is supplied (green LED U is shining), the contact remains in position 10-11 and the timing of the preset value t is commenced. After the preset time t has been counted down, the contact is shifted to position 10-12 (red LED is shining). The working sequence of the relay maybe repeated after turning the power supply off and on.
LAGGED  ACTIVATION - CYCLIC (D)
The Lagged Activation mode is triggered in equal work cycles according to the preset time values.
LAGGED  DEACTIVATION - CYCLIC (C)
The Lagged Deactivatin mode is triggered in equal work cycles according to the preset time values.
 


     

Attention!
Setting the time range knob regulator in the:
- ON - position with power supply activated connection of contact in position 10-12.
- OFF - position with power supply activated connection of contact in position 10-11.
