3.6.3 Signal input terminal wiring instructions:
A. AI analog input terminal:
Because weak analog voltage signals are particularly susceptible to external interfer-
ence, shielded cables are generally required, and the wiring distance should be as
short as possible, not exceeding 20m, as shown in Figure 3-12. In some occasions
where the analog signal is severely interfered, a filter capacitor or a ferrite core should
be added on the analog signal source side.
