Siemens APT brought a variety of low-voltage control products to the 14th China (Tianjin) International Industry Fair held from March 15-18. Siemens APT has launched the PB1...

1. Disconnect the control power supply: Before making the low-voltage terminal contact adjustment, the control power supply should be disconnected first to avoid the current directly or indirectly passing through the relay contact, and avoid electric shock or damage to the relay. 2. Open the relay cover: Open the relay cover, you can see the inside of the relay.

1. The type and series of relay selection First of all, the type of relay is selected according to the work requirements of the object to be controlled or protected, and then the appropriate series is selected according to the sensitivity or accuracy requirements. When choosing a series, you should also pay attention to the compatibility of the relay with the system. (1) ...

1. When choosing the solid state used in the printed circuit board with small current specifications, because the lead terminal is made of high thermal conductivity material, the welding should be carried out under the condition that the temperature is less than 250 °C and the time is less than 10S.

On August 26, the CAIMRS2022 China Automation + Digital Industry Annual Conference was held in Beijing. Based on the fields of automation, digitalization, industrial robotics and industrial interconnection, this conference shared top digital innovation ideas, discussed the latest trends in the industry, and how to grasp the new round of science and technology.

1. Most of the multiple values can be seen from the nameplate attached to the instrument, which will show the style of the value/value, which can be known by dividing the previous value by dividing the back value when calculating the standard core-piercing turns. If the actual number of turns of the grommet does not conform to the standard, then the multiple should be ...

The voltage transformer output is usually 100V 1. The working impedance in the secondary circuit of the voltage transformer should not be too small to avoid overload operation. 2 Before connecting the circuit, the polarity of the voltage transformer should be verified. 3 After connecting the circuit, the secondary coil should be reliably grounded, ...

When the solid state relay is open and there is voltage at the load end, there will be a certain leakage current at the output end, and care should be taken to prevent electric shock when using or designing. When the solid-state relay fails to be replaced, the original model or the product with the same technical parameters should be selected as far as possible, so as to match the original application line and ensure that the system ...

1. Why does the indicator light still glow after the control power supply has been disconnected? This situation is caused by the presence of interference voltage, and this problem can be solved by ordering our anti-interference indicator light 2. What are the operating hours of the AD16 series indicators? More than 30000 small ...

(1) The influence of the internal resistance R2 and leakage impedance X2 of the secondary coil on the error: when R2 increases, the specific difference and angular difference increase; As X2 increases, the specific difference increases, but the angular difference decreases. Therefore, to improve the error, R2 and the appropriate X2 value should be minimized. Due to the secondary coil internal resistance R2 and leakage ...

1. The position of the auxiliary contact is not suitable. After the switch has been tripped, the mechanical part has moved, worn phenomenon, resulting in the auxiliary contact position offset to the correct position, in the protection action tripping, when the auxiliary contact is not disconnected, the outlet electrical appliances, electrical appliances, relays have returned, and it is ...

1) Electromagnetic relay: an electrical relay that works by using the suction force generated by the circuit in the input circuit between the electromagnet core and the armature. 2) Solid relay: refers to a kind of relay in which electronic components perform their functions without mechanical motion components, and the input and output are isolated. ...

merit 1. High life, high reliability: solid state relay has no mechanical parts, the contact function is completed by solid devices, because there are no moving parts, so it can work in a high impact and vibration environment.

According to the principle of action, it is divided into: 1. The rectifier relay is used in the AC circuit, and its electromagnetic system, contact system and action principle are the same as those of the DC stepless relay. 2. Transistor relay: Transistor relay is composed of transistor transmitter or zero indicator, logic relay, transistor relay.

1. Some common faults of high-voltage relay coils 1. The common fault cause of the coil is often disconnected: whether the ultrasonic wave is used to clean the high-voltage relay, or whether the overvoltage is added to the coil will also promote the probability of the coil being disconnected. 2 ...

1. Before the installation of the open current transformer, it must be connected to the meter (or other measuring devices) for the second time to ensure that the transformer is not open for the second time; 2. Place all the open current transformers connected to the secondary line on the site and wait for installation; 3. If the on-site bus is electrical...

When the current transformer is finalized and its internal parameters are determined, the magnitude of the error will be affected by the secondary current (or primary current), secondary load, power factor, and frequency. These factors are called external factors, and the error of the current transformer in operation is mainly affected by these four factors. ...

1) The wiring of the current transformer should comply with the principle of series connection: that is, the primary winding resistance should be connected in series with the tested circuit, while the secondary winding resistance should be connected in series with all instrument loads 2) According to the size of the measured current, select the appropriate transformation ratio, otherwise the error will increase. At the same time, one end of the secondary side must be grounded in case ...
