2.5.2 Wiring of control circuit terminals
●Wiring of analog input terminals
AI1/AI2 terminals accept analog signal input, toggle switches SW1 and SW3 select the input voltage (0 ~ 10V) or
the input current (0 ~ 20mA). AI3 (exclusive for 35R5GB and above models) terminals accept analog signal input,
toggle switch SW4 selects the input voltage ( - 10 ~ 10V) or the input current (-20 ~ 20mA). The wiring of terminals
is shown in Fig. 2-14:

Wiring of analog output terminal
In S2R4GB ~ 3004GB, analog output terminal AO1 external connecting analog meter can indicate a variety of
physical quantities. Slide switch SW2 selects the output voltage (0/2 ~ 10V) or the output current (0/4 ~ 20mA). The
wiring of terminals is shown in Fig. 2-15:
