◆ Analog input terminal instructions

The AI1 and AI2 terminals can accept both analog voltage input and analog current input. They
can be switched by jumpers "AI1" and "AI2" on the IO board. The connection method and jumper
switch configuration are shown in the following figure:
The AO1 and AO2 terminals support the voltage output (0~10V) and the current output (0~20mA). They are
selected by jumpers "AO1" and "AO2" on the IO board. The connection method is as shown in the figure below:
