开关量输出为继电器输出,可实现“遥控”和报警输出。
开关量输入是采用开关信号输入方式,由外部电源供电。当外部接通或断开时,经过仪
表开关输入模块采集其接通或断开信息并通过仪表本地显示。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。
Switching output is relay output, can achieve the remote-control and alarm output.
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.
