Overall and installation dimension(mm):
- Q: Thermal overload relay
- Thermal overload relay function: 1. Under normal circumstances, turn on and off the high voltage circuit in the no-load and load current. 2. In the event of system failure with the protection device and automatic device to match, quickly cut off the fault current, to prevent the accident to expand, so as to ensure the safe operation of the system.
- Q: Thermal relay
- If the thermal relay is connected in series with the three-phase motor, then its role is when the motor overload occurs when the motor will appear temperature rise phenomenon, the final motor burned. After the thermal relay is connected in series, the opening and closing of the thermal relay is in the control circuit, thereby controlling the power off of the motor or (after resetting) the power supply (protection motor)
- Q: Mitsubishi Q series relay L and M difference
- I generally understand that L is a live hold of M, want to reset L, must be reset by instruction (eg RST).
- Q: Whether the thermal relay and the fuse can use only one of them can play short circuit and overload protection role
- Can not, you can replace a motor protector can meet the two requirements!
- Q: Plc relay why soft relay
- Soft relay PLC user program (software) instead of the relay control circuit (hardware) The relay in the PLC equivalent circuit is not the actual physical relay, it is essentially the state of the memory cell. Unit status is "1", which corresponds to the relay connected; unit status is "0", then the relay is off. Therefore, we call these relays "soft relays". So the number of "soft relays" contacts is infinite and can be understood as a programmable controller. (SOLIDSTATE RELAYS) is not the same thing, state relay abbreviated as "SSR", is a kind of solid electronic components by the composition of the new non-contact switch devices, which use electronic components (such as switching transistor, Silicon and other semiconductor devices) switching characteristics, can be achieved without contact without sparking the purpose of turning on and off the circuit, it is also known as "non-contact switch", it came out in the 1970s, because of its non-touch Point of work characteristics, so that in many areas of electronic control and computer control has been increasingly widely used. The "contact" of the soft relay in the PLC corresponds to the state of the flip-flop in the chip. The state of the flip-flop is only two, high and low, that is, 1 and 0. When you want to use it, Come out, and then put it into a register, and then operation, so that it can be used indefinitely. Root ordinary than with the following characteristics 1, the reaction speed, low noise, low energy consumption. small volume. 2, powerful, easy programming, you can always modify the program, 3, high precision control, can be complex program control. 4, can control the process of automatic detection. 5, the system is stable, safe and reliable.
- Q: Direction impedance relay why there is a dead zone?
- The characteristic circuit of the direction impedance relay passes through the origin, and when the short circuit occurs on the protection outlet, the residual voltage on the line is 0, and the amplitude and phase can not be compared. Therefore, the protection can not be performed.
- 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: Can the intermediate relay contact be engaged for a long time?
- Generally according to the needs of the work, can be long-term pull
- Q: Why is the heater with solid state relay better? Switching frequency is not high, why still use solid state relay? After all, too expensive.
- (1) solid state relays because there is no mechanical parts, so in high impact, vibration environment, due to the composition of solid-state relay components of the inherent characteristics, so the solid state relay determines the long life, high reliability. (2) Solid state relays have a wide input voltage range, low drive power, and are compatible with most logic integrated circuits without buffering or drivers. (3) solid state relays because of the use of solid devices, switching speed from a few milliseconds to a few micro (4) solid state relay does not enter the "coil", no contact arcing and bounce, thus reducing the electromagnetic interference. The solid state relay is powered by a zero voltage switch that reduces the sudden interruption of the current waveform, thereby reducing the switching transient. So still use solid state relays
- Q: Relay on the MC, NO there COM mean what?
- NO - Normal Open, that is often open (contact), normal (no power) when the state
