ABB PFSK151 3BSE018876R1 3BSC980006R358传输速率较低，在异步传输时，波特率为20Kbps。

接口使用一根信号线和一根信号返回线而构成共地的传输形式，这种共地传输容易产生共模干扰，所以抗噪声干扰性弱。

传输距离有限，大传输距离标准值为50英尺，实际上也只能用在50米左右。针对RS-232-C的不足，于是就不断出现了一些新的接口标准，ABB PFSK151 3BSE018876R1 3BSC980006R358就是其中之一 

ABB PFSK151 3BSE018876R1 3BSC980006R358 has a low transmission rate of 20Kbps in asynchronous transmission.

The interface uses a signal line and a signal return line to form a common ground transmission form, which is easy to produce common mode interference, so the anti-noise interference is weak.

Transmission distance is limited, the maximum transmission distance standard value is 50 feet, in fact, it can only be used in about 50 meters. In view of the shortcomings of RS-232-C, some new interface standards continue to appear, ABB PFSK151 3BSE018876R1 3BSC980006R358 is one of them
