Analog Wiring
Wiring to the built-in analog I/O terminals of the CPU module is explained below.
Analog input wiring

Class D
grounding
*1 For analog input wiring, use shielded twisted-pair cables (double-core type). Separate them from other power lines or lines which can be
induced by others.
*2 For unused channels, short-circuit the "V+" and "V-" terminals.

Class D grounding
*1 For analog output wiring, use shielded twisted-pair cables (double-core type). Separate them from other power lines or lines which can
be induced by others.
*2 Ground a shielded cable at one point on the signal receiving side.
