Overall and installation dimension(mm):
- Q:Teachers, I do not understand the level controller connected to the liquid level on the high, medium and low three lines is the use of what principle to send signals to the controller, ask you. Thank you!
- Level control relay connected to the liquid level of the sensor line principle: Level relay is the control of the liquid level of the relay, the use of liquid conductivity, when the liquid reaches a certain height when the relay will action to cut off the power. When the liquid level is lower than a certain position, the power is turned on to make the pump work and reach the function of automatic control. Automatic control consists of sensors and control actuators. The liquid level controller's sensor is generally a wire. The use of water conductivity. Water conductivity is poor, can not directly drive the relay. So there must be electronic circuit to amplify the current to promote the relay work. High level for the water level overflow point, free control of water level, the water level to automatically stop; low line for the automatic water point, the water level at this point automatically start the water device; midline for the regular contact.
- Q:What is the relay return factor?
- Is the ratio of the return value of the relay to the value of the action. Such as over-current relay return factor is Return coefficient = return current / operating current,
- Q:When to use intermediate relay
- 1, signal detection, transmission, transformation or processing, the use of intermediate relays, such as the use of metering flicker and so on. 2, the control system output signal and the load side of the electrical isolation; such as the control system output signal for the DC12V, but the load using AC380V power supply. 3, the controller output signal with the load capacity is often limited, in the mA or A level, if there is a need for greater current load, only through the intermediate relay to convert. 4, easy to maintain. When the intermediate relay contacts are damaged due to frequent use, it is easy to replace by simple plug.
- Q:Single cycle time relay and double cycle time relay What is the difference
- You say that the single cycle time relay can only set a time, after the start of the timer, the time after the relay relay action and maintain the state after the action; if you want to restore the original state must be reset or disconnect the power plus power.
- 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
- Contactor: is used in the main circuit system, control a single device, such as a motor, is also a switch, but it can be controlled, such as with the relay control, suitable for frequent action, but the general capacity is relatively small, no protection , The accident can not trip their own; Circuit breaker: also used in the main circuit system, you can control a single device, but also control multiple devices, but not suitable for frequent action, the capacity can be made a great, there are protection, the accident can trip their own; Relay: it is auxiliary circuit, can not pass large current, is typical of "small" things control "big" thing. To give an example, a line with a small motor, the motor to open 5 minutes to stop for 5 minutes; this should be installed in the circuit outlet circuit breakers, when the motor problems in a timely trip in the motor power inlet string into the contactor, Use it to actually control the motor on and off, with a relay composed of 5 minutes delay circuit to control the contactor.
- Q:OMRON relay G9EA-1 PDF data there Electrical endurance (See note 6.): 400 VDC, 30 A, 30,000 Ops / min. 400 VDC, 60 A, 3,000 Ops / min. 120 VDC, 100 A, 3,000 Ops / min. And now do not understand what this means! Look under the detailed instructions There is trouble to recommend a relay can be placed on the PCB board Requires electric shock voltage 300VDC because I want to give a group of charge to 300V capacitor discharge instantaneous current is about 1200A away Trouble to recommend a relay can be placed on the PCB board Requires shock voltage 300VDC because I want to give a group of charge to 300V capacitor discharge current is about 1200A
- Is not you wrong, the relay can not do so the use of high frequency, the relay life has 30W times the argument, that life is 30W times, 400 VDC, 30 A, 30,000 Ops / min. 400 VDC, 60 A, 3,000 Ops / min. 120 VDC, 100 A, 3,000 Ops / min It should be said that the relay in the case of 400VDC.30A can do 3W times 400VDC60A can do 3 thousand 120VDC100A can do 3 thousand times, but I can tell you that this is impossible to do, or is the product price wrong , If it is 400VAC30A is no problem, I was doing relay life test,
- Q:The work of the car relay, such as five-pin relay they are what the role of each line of the details of the details of the more detailed the more grateful
- 85 and 86 are coils, then positive and negative! 30 and 87a is a closed point, the relay is not energized when the two corners are connected, power off after! 30 and 87 are often open, the principle and 87a the opposite!
- Q:Input relay, the role of output relay.
- Factory specializing in the production of various types of time relay electromagnetic relay electronic relay high-power relay level relay solid-state relay high-power relay small relay timer counter relay. Relay is essentially a signal transmission of electrical appliances, it is based on the input signal to achieve different control purposes. The relay is typically used to turn on and off the control electronics (motor) Such as in the DC motor in the current relay, when the current is too small or too large, it detects the current signal after the control of the motor start and stop There are such as thermal relays, such as long-term overload of the motor leaving the temperature is too high, it will control the motor to stop
- Q:Transistor and relay PLC is how is it? There are leakage and so on
- Transistor PLC and relay PLC in the output at low frequency work no difference But the transistor has a one-way continuity, can only use the DC power supply, if the use of AC power, it may lead to the point of reverse breakdown and burned. The relay does not have too many requirements, but in the high-frequency output when the relay jitter, if the system scan fast, the relay jitter signal will be scanned and input into the system, causing malfunction. And the transistor does not exist this problem, it can quickly respond to system requirements (this is the PLC selection should pay attention to the problem, generally do not require a quick response, select the relay PLC good point, which I personally think) Also, PLC in the use of time, we must pay attention to their use of the PLC is the source or the type of leakage. This is related to the public termination of the problem is still negative. Such as Japan's Mitsubishi PLC for the leakage type, while the majority of Western Western PLC source. What else can not understand me?
- Q:Plc relay why soft relay
- Because the relay in the PLC is not visible outside, change the control does not need to re-wiring, as long as the re-programming just fine!
