Wiring of analog input terminal
3.3.3.1
Wiring of AI1 and AI2 terminals with analog voltage signal:
When the AI2 terminal is in the mode of analog voltage signal input, the switch S2 on
the terminal block is set to the voltage mode, as shown in Fig. 3-12.
When the analog voltage input signal is powered by an external power supply, the
wiring of terminals AI1 and AI2 is shown in Fig. 3-12-a.
When the analog voltage input signal is sent by a potentiometer, the terminals AI1 and
AI2 are connected as shown in Fig. 3-12-b.
