Time relay DC 12V 24V

Q: With a SJ11 relay and normally open proximity switch to form a control circuit, to close the switch in place after a certain period of time after the cycle of work: Oh. Got it. 1, the workpiece close to the switch, the time relay action, (speed) motor immediately stop, chain equipment immediately shut down.

Q: Switching power supply to Canada NRcan energy efficiency time about how long: To ensure that the charger and battery voltage uniforms, your battery is 25.6v of the job, 65AH is the battery capacity

Q: My family has a Gree 1p air conditioning, before the use of normal. The recent start-up leakage protection switch to automatically trip. Maintenance personnel to check that the compressor leakage. After the replacement of air conditioning is not detected after the leak. But now with heating about half an hour or tripping. But the socket ground after the break is not the case. Maintenance staff said that the ground contact is not good. May i say what? If my air conditioning is not connected to the ground, will there be any danger ah? (My home when the leakage protection switch 40A) Thank you!: Maintenance staff said wrong, the ground is not broken after the trip, indicating normal air conditioning grounding, leakage protection work is normal, and can rule out over-current trip, so your home air conditioning is still the problem of leakage to the ground. Although in your supplementary that guy seems to have some truth, but who can guarantee that the leakage switch is never a problem, if the air conditioning switch when the switch does not jump, the consequences you think about it, say he is equal to let your home air conditioning Sick work, you can feel comfortable? Enjoy the progress of science and technology to bring our comfort, is to ensure that our own security as the premise, so I think you should not compromise, air conditioning is a certain problem, the ground is also must be connected, because life is above everything!

Q: Transistor 8050 do switch circuit response time how long, zero a few seconds?: Although the switch application, the speed is slower than the amplification, but how far it is impossible to zero a few seconds!

Q: 1, how can the length of a switch in the PLC to control the length of the output voltage? The longer the input switch closure time, the higher the output voltage, which type of PLC to choose? 2, in the input to a signal, the PLC internal program can control the output voltage from a specific value of a linear transformation to another value? 3, PLC can directly drive the load? The load is a DC solenoid with a power of 30W.: You can need to add analog expansion module but is a level of voltage changes rather than stepless changes should be used to control the timing is only a very short time interval and the output of the analog signal and then through the amplifier output control voltage on the line because the PLC The rated voltage on the point of the estimated that you can not reach the requirements of the PLC is not directly add the load are generally added to the middle of the relay or the rules do not lose the craft Oh

Q: The diode is a switching element, and its switching time includes what and what: The general reverse recovery time is greater than the opening time, so the use of switching diodes on the parameters only gives the reverse recovery time. Switching diode switching speed is quite fast, like silicon switching diode reverse recovery time only a few nanoseconds, even germanium switching diodes, but also a few hundred nanoseconds.

Q: During the day automatically power off, night fixed time bright, called what switch?: Electronic switch, intelligent switch: intelligent switch is widely used in home intelligent transformation, intelligent office transformation, industrial intelligent transformation, agriculture, forestry, animal husbandry, intelligent transformation and other fields, greatly saving energy, improve the efficiency and Reduce the operating costs, the real smart line to do the world.

Q: This time control switch how to set the control time: Press the "time" button, the bottom left of the display appears "1 off" words (that the first off time), then press the "school week", "school", "school" key, enter the required closure Date (note: off date must correspond to open date) and time; Press "timed" button, the lower left of the display will display "2 open, 2 off, 3 open, 3 off, ........, 10 open, 10 off", refer to steps 2,3 After each switch time; If you do not need to set 10 groups of switches every day, you must press the "Cancel / Resume" button to erase the time of the remaining groups to display the "- -: - -" pattern on the display (not 00:00)

Q: Time timer switch time timer switch: The timer is really a great invention, so that a lot of people need to control the time to work a lot easier. People even use the timer in the military, made a time bomb, regular detonator. Many household appliances are now equipped with a timer to control the switch or working hours.

Q: The total switching time of the transformer on-load tap-changer is probably how much: The total switching time is obviously the total time to complete the whole process, the same period refers to the three-phase switch breaking and closing the same period.
