RS485 Communication
Analog Voltage/Current Input 1
Analog Voltage/Current Input 2
Note ：
1 +10V Max.Output:50mA
Note: 1.When connect solar panel, please connect PV+/PV-.
2.The communication interface of the PCE is considered as DVC A. The external signal communication interface is
considered as SELV. The compatibility shall be considered when the communication interfaces are connected.
