Tc560V2 3BSE022178R1ABB电磁干扰源及对系统的干扰

1干扰源及干扰—般分类

影响PLC控制系统的干扰源与一般影响工业控制设备的干扰源一样，大都产生在电流或电压剧烈变化的部位，这些电荷剧烈移动的部位就是噪声源，即干扰源。

干扰类型通常按干扰产生的原因、噪声干扰模式和噪声的波形质的不同划分。其中∶按噪声产生的原因不同，分为放电噪声、浪涌噪声、高频振荡噪声等;按噪声的波形、质不同，分为持续噪声、偶发噪声等;按噪声干扰模式不同，分为共模干扰和差模干扰。共模干扰和差模干扰是一种比较常用的分类方法。共模干扰是信号对地的电位差，主要由电网串入、地电位差及空间电磁辐射在信号线上感应的共态(同方向)电压迭加所形成。共模电压有时较大，特别是采用隔离能差的配电器供电室，变送器输出信号的共模电压普遍较高，有的可高达130V以上。

TC560V2-3BSE022178R1共模电压通过不对称电路可转换成差模电压，直接影响测控信号，造成元器件损坏(这就是一些系统IO模件损坏率较高的主要原因)，这种共模干扰可为直流、亦可为交流。差模干扰是指作用于信号两极间的干扰电压，主要由空间电磁场在信号间耦合感应及由不平衡电路转换共模干扰所形成的电压，这种直接叠加在信号上，直接影响测量与控制精度。

Product description

TC560V2 optical modem. Optical expansion of the DS 100 PBC expansion bus. For optical fiber 2x50/125 or 2x62.5/125um. ST type connector.

The optical modem signal is connected between the receiving photoelectric converter, the central processor and the transmitting electro-optical converter, and the broadband RF optical signal is converted and loaded, and then transmitted through the transmitting electro-optical converter for optical fiber. Because the invention adopts a bidirectional receiving photoelectric converter and a transmitting electro-optic converter to connect with a computer for signal modulation and decoding, the broadband RF signal can be directly converted into an electrical signal, and then transmitted to the optical train by the transmitting electro-optic converter. The equipment used has the characteristics of simple structure, no distortion of broadband RF signal, and fast signal conversion speed. It is suitable for application in the modulation and demodulation of wideband RF optical signal.

Tc560V2 3BSE022178R1ABB Electromagnetic Interference sources and interference to the system

1 Sources of interference and interference - General classification

The interference source that affects the PLC control system is the same as the interference source that generally affects the industrial control equipment, which is mostly generated in the part where the current or voltage changes dramatically, and the part where the charge moves violently is the noise source, that is, the interference source.

Interference types are usually divided according to the cause of interference, noise interference mode and noise waveform quality. Among them: according to the different causes of noise, it can be divided into discharge noise, surge noise, high-frequency oscillation noise, etc. According to the different waveform and quality of noise, it can be divided into continuous noise, accidental noise, etc. According to the different noise interference modes, it can be divided into common mode interference and differential mode interference. Common mode interference and differential mode interference are commonly used classification methods. Common-mode interference is the potential difference between the signal and the ground, which is mainly formed by the superposition of the common state (same direction) voltage induced by the power grid, the ground potential difference and the space electromagnetic radiation on the signal line. The common mode voltage is sometimes large, especially when the distributor power supply room is used with poor isolation energy, the common mode voltage of the transmitter output signal is generally high, and some can be as high as 130V or more.

TC560V2-3BSE022178R1 common mode voltage can be converted into differential mode voltage through asymmetric circuit, which directly affects the measurement and control signal, causing damage to components (this is the main reason for the high damage rate of IO modules in some systems), this common mode interference can be DC or AC. Differential mode interference refers to the interference voltage between the two poles of the signal, which is mainly formed by the coupling induction of the spatial electromagnetic field between the signals and the conversion of common mode interference by the unbalanced circuit. This voltage is directly superimposed on the signal and directly affects the measurement and control accuracy.
