*1 Handle the power supply circuit properly in accordance with "Power Supply Wiring."
*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] and [24V] terminals of the CPU module.
The service power supply or external power supply can be used for all inputs (X) of the CPU module. However
you need to select either one for each CPU module or I/O module. Both power supplies cannot be used
together in the same module.
