Wiring the power supply

When wiring the power supply, connect it to the POWER IN terminal of the power supply connector of the safety remote I/O
module.
Transition wiring of the power supply
When installing multiple safety remote I/O modules, the power can be supplied to the modules through transition wiring.
For transition wiring, connect wires between the POWER OUT terminal of the safety remote I/O module that will be the power
supplier and the POWER IN terminal of another safety remote I/O module that will be a power supply destination.

*1
*1 The largest current flows from the power supplier to the power supply connector of the first safety remote I/O module. Make sure that the
current does not exceed the current capacity (8A/pin) of the power supply connector. For a power supply to supply 24VDC, use a power
supply (SELV power supply) that does not exceed 30VAC (effective value), 42.4V (peak value), or 60VDC. Also, use a power supply
which is applied to "limited-energy circuit" defined in IEC61010-1.
(1) Power supply
For transition wiring, check the current consumption of each of the wired safety remote I/O modules.
For the current consumption of a safety remote I/O module, refer to the following.
