Analog input
+10V
Analog input
reference
voltage
10V ± 1%, internally isolated from COM
The maximum output current is 20mA
GND
Analog ground
Internal isolation from COM
AI1
Analog input
channel 1
0~10v: input impedance 22kΩ
0~20mA: input impedance 500Ω
The switch between 0~10V and 0~20mA analog input is
realized through dial switch S300, and the factory default
voltage is input.
