Rastîn Rewlay

Bi rêbêkîn sade, relêya elektrîkî di vê şekilda nîşan dida. Lî hûn fixed coil di tîpa pêşdestkirina wergera. Heke dîmaya ji bo fixed coil bipejebet da ku ber bi pick up value, plungera fers heye da ku jî bibe veqetandî û NO contact (normally open) bibe bendrawe. Wergera relêyek wekî ya çend e. NO contacts relêyek bendrawe di dema ku dîma ji bo fixed coil bipejebet da ku ber bi pick up value. Ev ê misalî sade yê relêya bi deyêkîne. Cunkî idealî yên tu ne dema delay ne di navbera dema ku dîma actuating bipejebet da ku ber bi pick up level û dema ku NO contacts bendrawe.

Pêşdestkirina Relêya Bi Deyêkîne

Relêya bi deyêkîne wê ye ku ji bo dema delay tune ne hatine pêşdestkirin. Diha tune idealî yên tu ne dema required ne ku relêyek bike operasyon. Heta ew ku hûn dikarin dema delay ku tune ne xwe bine destniyara.

Çunkî current coil inductor e, hûn dikarin dema delay ku reach the current in the coil to its maximum value. Heta ew ku hûn dikarin dema required ku mechanical movement plunger in the relay. Ev dema delays inherent in the instantaneous relay but no other time delay is intentionally added. Ev relêyek dikarin operasyon bike li ber 0.1 sec.

Misale Relêya Bi Deyêkîne

Hebe zanyari girîng relêyek ku bi deyêkîne ne. Wê misalî attracted armature relay û lî hûn iron plunger electromagnetic be attract bikin relêyek. Heke attractive force electromagnetic crosses its pick up level, iron plunger starts move towards the magnet and crosses the relay contacts. The magnetic strength of the electromagnet depends upon the current flows the coil conductors.

Misalê din ê solenoid type relay. Heke current in the solenoid crosses pick up value, the solenoid attracts an iron plunger which moves to close the relay contacts.
Balance beam relay yê din ê well known example of relêya bi deyêkîne. Here balance of one horizontally placed beam is disturbed due to pick up current in the relay coil. Due to unequal torques at two ends of the beam, it starts rotating against the hinge and ultimately closes the contacts of the relay.
