Analog input
AI1 Analog input1
Receive voltage/current
input. Voltage or current
input mode are
selectable by
data-chosen-switch
SW1. Voltage input
mode is the default
mode, refer to
P4.00~P4.10 to set the
range.(The reference
ground is GND)
Input voltage range:
0~10 V
(Input resistance:
100 kΩ)
Input current range:
0~20 mA
(Input resistance:
500Ω)
AI2 Analog input2
