Q:Forward, the hair, three friends which relay is good: I personally used the yuan is the relay products, both in the service or products, in terms of cost-effective advantages. Their positioning mode is better, mainly to do small appliances category!

Q:Often positive, reverse and frequent start of the motor, suitable for thermal relay to protect. right?: For the special work reversing and breaking off the special work of the motor, should not use thermal relay as overload protection device, but should use the buried motor winding temperature relay or thermistor to protect.

Q:Can SLI-12VDC-SL-A and HJQ-15F-1 - 12VDC - S - Z (TBF - 1) be generic? What are the meanings of those English letters above? The The The The Can SLI-12VDC-SL-A and HJQ-15F-1-12VDC-S-Z be universal?: It seems that the coil is DC 12V, can be universal, that is, do not know their contact size

Q:I would like to ask: PLC output sub-relay output and thyristor output, what is the difference.I only control the general digital signal, what type should be selected?: So if you want to high-speed response or need to be smaller, select the transistor unit, if you need a relatively large current on the selection of the relay unit. Generally no special requirements, select the relay unit, wiring and measurement are very convenient, because there is no volume limit so are the terminal block, but the same number of points much larger. Input and output relay is the switch, and the transistor is analog! The switch is in the form of a switch, and the size of the input and output is independent of the switch. Carrying capacity is relatively strong. May drive loads such as relays! While the analog some of the signal amplification, and some of the A / D conversion. It can drive signals such as 1-10V, 4-20mA,

Q:Relay protection inside the said fit and what is the difference between: Fit refers to the circuit breaker in the closing position, the specific performance of HWJ closed, closing lights. KKJ is a relay of Nancy. Is the position after the combination, used to replace the previous KK handle after the position, the two series together to form the location does not correspond to the circuit to start the reclosing or accident total signal. KKJ is a two-position relay, hand-held (including remote) start KKJ, KKJ contact closed, manual / remote control when opening KKJ re-starting the coil at the same time, KKJ contacts off. While the protection trip does not start the reset coil (ie, KKJ is still closed when the protection trip). That is, when the circuit breaker in the closing position, KKJ contacts in the closed position, when the trip TWJ closed, and KKJ contacts in series together to start the reclosing or accident total signal can also be understood as the protection of the trip can To start reclosing, and hand points away from the points do not start reclosing. In general, after the general deep Rui and NARI continue to use, such as reclosing, prepared from the vote after the need to judge after the location, after the show that the hand jump, do not start reclosing and prepared from the cast.

Q:The relay is an electrical device that turns on or off the controlled output circuit when the input quantity (such as voltage, current, temperature, etc.) reaches the specified value. Circuit breakers such as the home of the light switch the total gate, but also a certain value will automatically break the trip ah ... how many people think they do not have comparable Where is the difference between their essentials? The The Popular point is why the light of my home can not use relay control to use circuit breaker control column: There are many kinds of relays in the circuit to be combined with the implementation of the device, such as current relay, when it detects the current exceeds the set value, will send a switch signal, and it itself can not disconnect the main circuit, because Its control ability is poor, the contact rated current is only about 5A, then it must be sent to the implementation of this signal, such as AC contactor, by the six-way contactor to control the main circuit through and off. The rated current of the circuit breaker is very large, can directly control the main circuit of the off, and the detection circuit in the circuit breaker inside, when a parameter exceeds the set value, it put the circuit to cut off. Give more points to it, playing so many words are tired!

Q:The relay is connected to the diode: Related information: Freewheeling diodes are often used with energy storage components to prevent voltage and current changes, providing access. The inductor can pass through it to provide continuous current to the load, so as to avoid the load current mutation, play a smooth current role. In the switching power supply, you can see a diode and resistor connected together constitute the freewheeling circuit. This circuit is connected in parallel with the transformer primary side. When the switch off, the freewheeling circuit can release the transformer coil stored in the energy to prevent the induced voltage is too high, breakdown switch. The general choice of fast recovery diodes or Schottky diodes can be used to generate the reverse potential of the coil through the current consumption of the form, we can see "freewheeling diode" is not a substantial component, it is only in the circuit To the role known as "continued flow".

Q:Why the relay back and forth fast jump between the two contacts can see an arc. Eliminate the problem of the relay itself: There are many reasons for this phenomenon: 1. Control voltage is low. 2. The relay coil rated operating voltage is greater than the control voltage. 3. Poor control of the control line. 4. AC relay copper core short circuit ring off.

Q:See the Omron relay (G6K-2F-Y) manual on the "non-latching" (non-latch) and "terminal spacing" these two terms, do not know what the meaning, please enlighten me, the best point: Is the "self-locking" contactor, in the contactor "self-locking" circuit, such as the simplest two-button "open" and "off", the contactor coil a connector, according to the coil voltage requirements, connected to a fire line Or zero line. When the button is turned on, the other connector of the coil is turned on by the button, providing the coil voltage, the contactor sucking and. When the button is broken, the button of this line of fire, through the contactor auxiliary contacts, continue to provide voltage for the coil, the contactor can also be connected to the state, which is the contactor "self-locking." If you want to disconnect the contactor, press the push button switch "stop", contactor power failure, disconnect the circuit. Contactor "interlock", such as the use of two contactors to control the motor anyway, the two contactors can not smoke at the same time, so the control of the two contactor coil is connected to each other by another, and in Three-button switch on the wiring is also cross-controlled. This double interlock, is to put an end to rely on the operation of the manual movement. There is no circuit, that do not understand, you can find a typical circuit diagram, you can understand this "self-locking" and "interlock."

Q:Often open and normally closed what is the meaning of seeking expert detailed instructions,: In the state of non-energized contact measurement of the pass, power is not long pass, and vice versa
