Terminal mark
Description
+24V~COM
Pr24V power supply for external devices, it is generally used for power
supply of digital input and output terminals or external sensors.
The maximum output current is 200mA
PLC
Input terminal for external power supply, it is connected with +24V as default.
When use external signal to drive D8~D10, PLC terminal should connect with
external power supply, and meantime to disconnect PLC and +24V.
D8~D10
Digital input terminals, optocoupler isolation, compatible with ambipolar input
(NPN and PNP), input resistance is
4.7kΩ, voltage range is 9V~30V
Y1~Y2
Open collector output, optocoupler isolation:
Output voltage range: 0V~24V
Output current range: 0mA~50mA
Note: the terminal COM and CME are internal isolated, CME and COM are short
connected as default (24V is the power supply). When customers want to use
external power supply, CME and COM must be disconnected.
T2A~T2C
Relay output, C is the common port, A is the normal open port, B is normal close
port, the driven capacity is:
AC 250V, 3A.
DC 30V, 1A.

10.4 Communication Extension Card
10.4.1 Introduction of communication card
Communication extension card is used to extend the communication terminals for inverter. It is specially
used for Modbus communication function, and the card adopts electrical isolation design. The
communication card’s model No. is: KE600-RS485-02 It is connected with J8 on the control board.
The communication card provides the following terminals:
Communication interface: 1 channel, standard RS485 interface.
As shown in figure 10-5, jumper J3 is used to connect the terminal resistance of RS485 communication, to
connect with the left two PINs, the resistance is effective.
