Notes:
1. Analog signal input to AI1/AI2 (voltage or current) can be selected by
Data-chosen-switch, the default is voltage input. You can refer P4.00～P4.10 to
set the range.
2. Max output current of control circuit terminal 10 V is 30 mA.
3. The cable between PLC and 24 V terminals should be connected firmly
(S2R4GB～3004GB should be sure to disconnect the cable JP1 between PLC and
24 V; 35R5GB/37R5PB～3500G should be sure to disconnect the cable between
PLC and 24V), otherwise input terminals X1-X8 couldn’t work properly(in
