报警输出。开关量输入不仅能够采集和显示本地的开关信息，同时可以通过仪表的
RS485
实现远程传输功能，即“遥信”功能。
The switch input adapts the method of on-off signal input and powered by outer power supply.
It can be gotten by meter when there is a change of on or off via a switching input module. The
parameter of switching input can not only get and show the state of local switching information
but also achieve the communication via RS485, which called “remote information” function.
