DC input wiring
This section describes the wiring to the DC input terminal. The polarity of the common can be either way, as the signal is input
through the diode bridge. Note that the common terminal is common to each of four points. (Example: X0 to X3)
Consider that the constant amount of input current of 4.2mA TYP. (3 to 5mA) flows at power-on regardless of the input
voltage, when selecting connected devices and performing wiring.
