各位大神好。
要求设计一个接口板。其中有一个接口的两个输入信号的要求是:差分输入,低电平有效和差分输入高电平有效。这是啥意思?
求原理图分析。
具体要求如下:
J1-10 | CloseDoor light ( differential input ,low side) | 输入 | This is connected to ground externally. |
J1-12 | OpenDoor light(differential input, high side) | 输入 | +24V is supplied to this input when the OpenDoor light switch is active.
