- Q: I would like to delay 5 seconds after the power ..... instructions on the map can not read ah
- 2-7 power supply; 1-3 and 5-8 are normally open; 1-4 and 6-8 are normally closed; if only the delay selection 6-8
- 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
- The relay is to have a control line to play a role, if it is directly connected to the circuit it will always turn on. Circuit breaker can be directly connected to the circuit from the role of the switch.
- Q: Relay action
- The relay has several effects: 1) to expand the control range: For example, multi-contact relay control signal to a certain value, you can press the contact group of different forms, while switching, breaking, connected to multiple circuits. 2) Enlarge: For example, sensitive relays, intermediate relays, etc., with a very small amount of control, you can control the power of the circuit. 3) Integrated signal: For example, when a plurality of control signals are input into a multi-winding relay in a prescribed form, the comparison is carried out to achieve a predetermined control effect. 4) Automatic, remote control, monitoring: For example, the relay on the automatic device together with other electrical appliances, can be programmed to control the line, in order to achieve automated operation. The relay is an electrical control device. It has a control system (also known as the input circuit) and the control system (also known as the output circuit) between the interaction. Usually used in automated control circuits, it is actually a small current to control the operation of a large current "automatic switch". So in the circuit plays an automatic adjustment, security protection, conversion circuit and so on.
- 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: What is the relay?
- Many types of relays are pressure relays, time relays, temperature relays. The relay is a controller, such as a pressure relay, that is controlled to be connected or disconnected within a certain pressure.
- Q: Can the intermediate relay contact be engaged for a long time?
- Any relay, contactor are allowed to engage for a long time, but need to consider the contact can withstand the size of the current, temperature and other factors.
- Q: Relay on the MC, NO there COM mean what?
- These are abbreviations: NC - Normal Connected, refers to the state of the normally closed (contact), normal (without power)
- Q: What is the electronic relay code?
- Many types of electronic relays, the following list some of the more commonly used: K relay KA (NZ) current relay (negative sequence zero sequence) KD differential relay KF flash relay KH thermal relay
- Q: Overheating the work of the relay and the wiring method
- 2, thermal reed relay working principle and characteristics of thermal reed relay is a use of thermal magnetic materials to detect and control the temperature of the new thermal switch. It consists of temperature magnetic ring, constant magnetic ring, reed switch, thermal installation, plastic substrate and some other accessories. The thermal reed relay does not use the coil excitation, and the magnetic force generated by the constant magnetic ring drives the switch action. Whether the permanent magnetic ring can provide magnetic force to the reed switch is determined by the temperature control characteristics of the temperature magnetic ring.
- Q: Used to control the 220V solenoid valve and water pump Open the solenoid valve and then turn on the pump Turn off the pump and then turn off the solenoid valve
- With two relays for the job, but also add a time relay, or install a pressure switch plus a good relay, the detection of water pressure
