Digital input/output ports (DIN and DO1~DO4) are configured to collect node
data and control node communication.
For the RS485 communication ports (A1B1~A6B6), the communication
distance should be no more than 1,000m.
High voltage at AC power supply port! Live-line operation is prohibited. Before
wiring, make sure the input side is powered off and the grounding cable is
reliably connected.
Do not insert or remove the SD card while power is on.
