1Sec-999Min Pulse Signal Control Board Circuit\/ Motor\/ LED Delay Timer 12V 24V<br> Specifications:  <br> DC: 5-30V DC<br> Maximum current: 20A (greater than 5A need to heat sink)<br> Quiescent current: 20mA<br> Working current: 50mA<br> Working voltage: 5~30V DC<br> Signal voltage: DC DC4V~27V (commonly used in power <br> supply， or PLC， PNP sensor， signal， etc.)<br> Service life: unlimited switch<br> Working temperature: -40~85\u2103<br> Size: 64 x 40 x 13mm<br>  <br> Features:  <br> 1， to achieve high frequency and fast frequency switching circuit.<br> 2， the process will not produce noise.<br> 3， no electric spark.<br> 4， there will be no electromagnetic interference.<br> 5， the service life is longer than the commonly used electromagnetic relay. Often used in motor control， light bulbs， LED lamps， DC motor， micro pump， solenoid valve， etc.<br> 6， input and output the optocoupler isolation， enhance the ability to resist interference power， to ensure the stability， industrial grade circuit board， PLC， set parameters of power can be memory forever， the signal terminal can be for a long time to keep the voltage signal.<br>  <br> Circuit board function:  <br> 1， the signal triggers the output to start work， the time is up， the stop work， the delay timeA: once again， the invalid B: once again， the re - timing C: again， the stop reset<br> 2， the signal triggers the start time T1， the time to the output of the T2 to disconnect (reset)<br> 3， the use of the loop: on T1， disconnect T2， infinite loop. T1 and T2 are adjustable.<br> 4， there is a signal， the output of the work， to maintain the work， the signal disappears， start time， time to the output stop working， in the delay period， once again to the signal， delay cancellation， the signal disappears， re time.<br>  <br> Package included:  <br> 1 x Signal Control Board Circuit
