The switch input is the switch signal input method, the instrument is equipped with +12V working power
supply, no external power supply is required. When the external connection is turned on or off, the on or off
information is collected through the instrument switch input module and displayed locally by the instrument.
The switch input can not only collect and display the local switch information, but also realize the remote
transmission function through the RS485 of the instrument, that is, the "remote signal" function.
Switch output is relay output, which can realize "remote control" and alarm output.
