*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 For source input wiring, short-circuit the [S/S] and [0V] terminals of the CPU module.
The 24VDC service power supply or external power supply can be used for all inputs (X) of the CPU module.
However a user needs to select either one for each CPU module or I/O module. Both power supplies cannot
be used together in the same module.
