HJS-DE1/2 Time relay

1. purpose
   HJS-DE1/2 The time relay is used as a component that acts immediately after power on and returns after power off delay , Used in AC or DC protection and automatic control devices , Make the controlled component get the required delay . This relay adopts 2 Position disc setting ,HJS-DE1/2 Delay range 0.1 second _{9.9 second , Gradation 0.1 second .HJS-DE1/3 Delay range 1 second} 99 second , Gradation 1 second . This series of relays also have instantaneous contacts , Users can apply more flexibly .

Ordering instructions

Please indicate the relay model when ordering 、 specifications 、 Number 、 Rated voltage or current of power supply 、 Structure type code and special requirements

Power off delay relay , When the coil of the time relay is energized , Each delay contact acts instantaneously , After the coil is powered off, the contact is in the delayed setting working state , When the set delay arrives , The delay contact returns to the initial state . Control a motor , It is required to press the stop button after a time delay , Restart the motor , In this case, the power-off delay relay is needed to realize the above functions .

The power-off delay type is due to its working state （ In the process of delay, there is no need to connect an external working power supply ） And the control contact pulls in the contact during the power-off delay （ When the normally open contact becomes connected, it should remain connected ; Normally closed contacts become open , It should remain disconnected ） Conversion particularity （ It is opposite to the working state of the contact of the conventional energized time delay relay ） To meet its control requirements . The power-off time delay time relay is composed of the earliest separation device （ Low delay accuracy 、 The delay time is short ）; Now use the corresponding programmable timing IC or cmos Counting and frequency division integration to complete the delay , Compared with , With high delay accuracy , The characteristic of long delay time . So as to meet the control occasions of long time-delay in power failure .
