Q:Photoelectric switch control time relay control AC contactor delay closed

Photoelectric switch relay is through the box or the container within the material flow, fall, making the photoelectric switch infrared or bright or dark optical reaction, the resulting photoelectric signal amplification circuit, so that the photoelectric switch relay closed. Because the flow of material and the speed of the fall soon, the photoelectric switch relay closed off frequently, can not be used by the transmission mechanism, so to install the time relay to extend the signal time so that the transmission mechanism has enough time to run, use.

Q:Proximity switch response time is one second or one minute

If the metal in front of the switch is not removed, will always respond (alarm)

Q:Time controller how to use the button switch with the realization of the button switch and time controller can stop, thank you teacher

Between the controller control point and the hand control point and inoculation control two sets of control plus conversion off, hand control

Q:I have found the event viewer in the boot event, ask what should be done next Ask God ...

Use the computer comes with shutdown function: open the command window (start - run - enter cmd), enter shutdown-a cancel the automatic shutdown function. Use third party software: find the software, open the settings, cancel the automatic switch function.

Q:How is the time switch?

Each manufacturer produced the time control switch is not the same. To be set according to the instructions. The general is to hold down the clock at the same time hold down hours or minutes.

Q:I have 200 13w lights and two computers, I use the 63A leakage switch, each time playing with a few hours and tripped, so repeated, would like to ask how to deal with? Thank you

1, not short-circuit problem (because of short circuit in any case, do not rule out the short-circuit point, the time interval can not work long after closing, continue to smoke, and instantly from short circuit into open circuit). ?????? 2, not load can not afford (because the leakage switch, leakage switch only for leakage when the action, no overload action function). ?????? 3, the biggest possible reason is because the kitchen is relatively humid, in the lamp connector, socket connector, control switch joints, leakage switch joints and other moisture, moisture is too large, resulting in leakage current, more than leakage switch action current (generally 30 mA ) And action, sunny weather may be better, rainy weather may intensify.

Q:Samsung mobile phone automatic switch machine set time where?

The [automatic power on / off] tick, set the required power off time. After the above operation, the phone will automatically switch the machine according to the set time.

Q:Time switch how to adjust the time

Microcomputer control switch is a single microprocessor as the core with electronic circuits and other components of a power switch control device, can be days or weeks of circulation and multi-time control of home appliances opening and closing. Time set from 1 second to 168 hours, can be set daily 1-4 group, and multi-channel control function. One setting is valid for a long time. Applicable to all kinds of industrial electrical appliances, household appliances, automatic control, both safe and convenient and save money. The output current can be 10-25A, both normal control 2200W to more power of electrical work. But also with the relay, contactor, and other control of a variety of other high-power power equipment.

Q:Timing socket timer socket can really switch through time?

Such as inplug hard candy wifi smart socket can also be used to control the phone, thousands of miles away can control everything at home, not yet to the end of the house, You can open the water heater, is not more advanced than the timing function!

Q:220KV circuit breaker on the nameplate to write the rated closing time of 50 ~ 80ms, power station frequency frequency 50HZ, if a cycle is 0.02s that is 20ms in the same period during the closing period how to maintain the leading angle to meet the requirements, and to introduce some of the more professional book

This is more difficult to solve the current problem is that the same period or also known as the synchronization, which is the generator port breaker equipment Why use foreign products because of it, Siemens, ABB and other giants in this side of the study earlier, hope this link The paper can give you some help
