Each I/O board is connected to the I/O bus.For the safety and integrity of the signal,before the signal enters the I/O board,the signal needs to be refurbished,such as upper and lower limit inspection,temperature compensation,filtering,these work can be done on the terminal board,or can be done separately.Call them signal conditioning boards.

每一块I/O板都接在I/O总线上。为了信号的安全和完整，信号在进入I/O板以前信号要进行整修，如上下限的检查、温度补偿、滤波，这些工作可以在端子板完成，也可以分开完成，完成信号整修的板现在有人称它们为信号调理板。
