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. The way they control is such that the normally open contacts of the photoelectric switch relay are connected to the time relay coil to control the time relay. Time relay delay disconnect contact to connect the transmission mechanism of the AC contactor coil, control AC contactor.

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: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.

The first question, here to use the PLC's analog expansion module, in the PLC by a switch the length of the closing time to control the output voltage level, you can use the timer in the program, the switch closed time to time, Time to reach a certain range, the program set the output voltage for the analog value, the longer the output of the analog voltage value is greater, as to choose the kind of PLC that there is no fixed index, because the major Mainstream manufacturers are equipped with analog modules of the expansion module, such as Siemens, Omron, Mitsubishi, etc., personally recommend the use of Siemens, Germany's product quality is excellent. The second question, where the input signal input is divided into two kinds, one digital, the second is the analog, which depends on what your input signal is specific, by the PLC internal program control output voltage by a The specific value is linearly transformed to another value, where it is first necessary to create a specific value for it and then change the refresh of your input signal to another value, where the program is achievable and, of course, A timing problem, but the timing unit by you, to be a linear time is naturally as short as possible, each scan cycle can refresh the output can solve this problem. The third problem, can not, the general PLC output is not used to drive the load, because the current is too large will damage the output point, which is a protective measure, it is not allowed to directly drive the load The above answer may be some missing or wrong, the shortcomings also hope that the sea Han, hoping to help you

Q:Site how to switch the headlamps how to adjust the time

If it is time control switch control, Such as setting the load for an open time 18:00, The time is 05:00

Q:I pressed a mini wireless router and I wanted to open the wireless network at 19 o'clock every day at 7 o'clock the next day.

Mini wireless router looks like no this function! The Maybe you said the mini-wireless router is the kind of portable AP, remember only the function of the bridge.

Q:There is no time to set the time, to switch the lights regularly. The volume is small, it is best to say under the price I would like to manually set the time to control the lighting Will there be no ah

This should not be a problem, spend money will not be too much, you can buy a timer control device (for example, micro-desktop fan timer is very good, small size), come back from the light relay power supply You can immediately get,

Q:I produced the power supply is output 12V and 5V two groups. Current is 2A. Will the normal aging time is how much the load should be connected to the number of normal. Please advise experts. Thank you so here.

The initial trial production can be 24 hours of aging, and take 10% of which for a long time aging (at least half a month) to ensure quality. Into the first five batches of 100% load aging 40 minutes, if no problem and then you can use 80% or 100% load aging 25-30 minutes. General power plants are the same operation. Aging conditions: Ambient temperature: 35 degrees Celsius Aging load: 80% of total power

Q:Configuration king how to set the time switch! For example, to 3:00 automatically open! To 5 points automatically off! Every day can be automatically performed by time!

Write the program in the command language If the local time to the number of points a variable is 1 or 0

Q:How to view and delete the computer switch machine time record?

Very simple way to solve it is that you remember your father last time with the computer and then when you put the machine on the time to tune the last time your father with the computer time and then start a computer start again after the time Back to normal time

Q:Kc316 t microcomputer time control switch how to adjust the timing switch

* If you do not need 6, 12 switch timer (clock) key, return to the actual time. * If you set the error or cancel the setting Press the (Cancel) key, then press again to restore the original setting. * When no setting is displayed (- -). 4, check: press (set) to check all set the time is correct. 5, modify: Please press the (cancel) button at the setting, and then reset the timer switch time and week. 6, the end of the check: press the (clock) key to end the check and set, display the clock. 7, manual control: press (manual) button, you can achieve random open or off or automatic operation. I spent half an hour to play the instructions according to the Oh! The
