*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 sink input wiring, short-circuit the S/S terminal and the 24V 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.
