●Wiring analog input terminal
AI1/AI2 can accept analog signal input, operate Data-chosen-switch SW1 to select input
voltage (0～10V) or input current (0～20mA).The wiring is shown as Figure 2-13:

●Wiring analog output terminal
In S2R4GB～3004GB, if the analog output terminal AO1 is connected to analog meters,
the various kinds of physical values can be indicated. Operate wiper switch SW2 to
select output voltage (0/2～10 V) or output current (0/4～20 mA).The wiring is shown
as Figure 2-14:
