4.2.2 Explanation on Power Supply System

(1) When a single power supply is used for a slave
As shown in the figure below, the output side of each module is isolated by a photocoupler.
As for control logic power, its power source is the 24V supplied to the communication board which converts
and distributes to the modules.
The control logic power GND and the communication board 24V GND are shared. Therefore, when power
is supplied by a single source, the isolation on the output side of the modules is not complete.
To provide complete isolation from the output side by separate power supplies as in the case of DIO
modules, follow "Isolation of the output system by separate power sources" on the next page.
