Relay delay pulling in circuit

Published:2011/8/29 1:45:00 Author:Jessie | Keyword: Relay , delay pulling in | From:SeekIC

Relay delay pulling in circuit is composedof theplane transistors BC107C, BC107B and some other external components. Since transistors have high current amplification coefficient and small collector current,the delay can reach 60s. If it requires lower, it should use the lower capacitors.
