TR-54628-22中文资料Time Delay Relays数据手册Macromatic规格书

描述 Description

Upon application of input voltage, a preset delay begins (T1).At the end of the preset delay, the relay is energized.When the input voltage is removed, the relay contacts remain energized for a second, independently adjustable preset time (T2). At the end of the second preset time, the relay is de-energized.Voltage must be applied for a minimum of 0.1 second to assure proper operation.Any application of the input voltage during the time (T2) will keep the relay energized & reset T2.When input voltage is removed, the relay contacts remain energized for the full time (T2).No external trigger switch is required.
