485 communication
485 communication terminal, adopting
the Modbus RTU protocol
PE/CGND
PE: When selecting PE through J10, it
can be used as the connecting terminal
of 485 communication shielded cable;
CGND: When selecting CGND through
J10, it can be used as the connecting
terminal of 485 communication shielded
cable
Relay output
