Timing relays PCU-511UNI

PCU-511 UNI

Timing relays are devised to time the control of industrial and domestic automatic control engineering systems (e.g. ventilation, heating, lighting, signalling, etc.).
Contact 1P.

Functioning
Operation mode:
*LAGGED ACTIVATION (IR)
After the power voltage is supplied, the contact remains in position 11-10 (and 8-7 for PCU-510) 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 11-12 (and 8-9 for
PCU-510). The working sequence of the relay may be repeated after turning the power supply off and on.
*LAGGED DEACTIVATION (IA)
 Until the relay is activated, the contact remains in the 11-10 (and 8-7 for PCU-510) position. After the power voltage is supplied, contact is shifted to position 11-12 (and 8-9 for PCU-510) 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 (and 8-7 for PCU-510). The working sequence of the relay may be repeated after turning the power supply off and on.
*LAGGED ACTIVATION - CYCLIC (CR)
The LA operational mode is triggered in equal interruption/work cycles according to the preset time values.
*LAGGED DEACTIVATION - CYCLIC (CA)
The LD operational mode is triggered in equal interruption/work cycles according to the preset time values.
 


 

Attention!
* 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 (and 8-9 for PCU-510).
  OFF - position (power supply activated) causes the contact to be permanently closed in the 11-10 (and 8-7 for PCU-510) 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.
