TR-54122-22中文资料Time Delay Relays数据手册Macromatic规格书

描述 Description

Upon application of input voltage, the time delay relay is ready to accept a trigger.When the trigger is applied, the time delay (t1) begins.At the end of the time delay (t1), the output is energized.When the trigger is removed, the output contacts remain energized for the time delay (t2). At the end of the time delay (t2), the output is de-energized & the time delay relay is ready to accept another trigger.If the trigger is removed during time delay period (t1), the output will remain de-energized and time delay (t1) will reset.If the trigger is reapplied during time delay period (t2), the output will remain energized and the time delay (t2) will reset.
