Analog Wiring

Wiring to the built-in analog I/O terminals of the CPU module is explained below.
For specifications of the built-in analog I/O terminals of the CPU module, refer to Page 40 Built-in Analog Specifications.
Analog input wiring
Shield *1
Class D grounding
(grounding resistance: 100  or less)
*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.
When used as a current input, refer to Page 185 How to Use Analog Inputs Built in CPU Module for Current Inputs.
Analog output wiring
*1 Shield
*2
Class D grounding
(grounding resistance: 100  or less)
*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.
