Analog input terminal
Because the weak analog signal will be easily affected by the external interference,
generally shielded cable shall be used, the cable length shall be as short as possible and no
longer than 20 meters, as shown in Fig. 2-5.1. In case the analog signal is subject to severe
interference, analog signal source side shall be installed with filter capacitor or ferrite magnetic
ring, as shown in Fig.2-5.2.
