Sequential Aspects of Relay Circuits

THE BASIS of relay circuit action is that a set of n of the 2-position devices can assume 2n distinct combinational patterns. Thus a particular input condition can produce a particular relay pattern which, by utilizing the contact configurations on the relays, generates a corresponding output condition. A new input condition develops another output condition, and so on.
