*1 Handle the power supply circuit correctly in accordance with Chapter 9 "Preparation for Wiring and
Power Supply Wiring Procedures."
*2 For an input device having a parallel resistance or a two-wire proximity switch, a bleeder resistance may be required.
*3 In the case of source input wiring, short-circuit the terminals of the extension units as well as
the S/S terminal and the 0V terminal of the main unit
*4 The "24V" and "0V" terminals are located on the output terminal side.
For details on the terminal layout, refer to Section 4.7.
