TD-71222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 (t) begins.At the end of the time delay (t), the output is energized and remains in that condition as long as either the trigger is applied or the input voltage remains.If the trigger is removed during the time delay (t), the output remains de-energized & the time delay (t) is reset.
