The ETN Series, Solid-State Flasher, Time Delay Relays, have 2-wire leads (Series Connection with Load), are totally encapsulated circuitry, has a molded case with built-in mounting feature and has high inrush capability. This series is low cost, and has 1 Amp (Full wave) and 3 Amp (half wave) versions. When supply voltage is applied, the OFF delay (T1) begins. Upon completion of the OFF delay, the load energizes and the ON delay (T2) begins. Upon completion of the ON delay, the load de-energizes and one cycle is complete. This ON/OFF cycling continues until the supply voltage is removed. The OFF delay always equals the ON delay.
