10.3 I/O Extension Card
10.3.1 Introduction of I/O card
I/O extension card is used to extend input and output terminals for inverter. The model No. is
KE600-DG-01. It is connected with J8 on the control board.
The I/O extension card provides the following terminals:
1, Digital Input terminals: 3 channels.
2, Digital Output terminals: 2 channels, open collector type output.
3, Relay output terminals: 1 channel, Normal Open and Normal Close.
4, Communication interface: 1 channel, standard RS485 interface.
As shown in figure 10-3, jumper J5 is used to connect the terminal resistance of RS485 communication, to
connect with the top two PINs, the resistance is effective.
