Note
Be sure to separate the communications power supply, the internal
power supply for the Communication Unit and the CPU Bus Unit, and
the power supplies for the I/O Units. If the same power supply is used,
malfunction due to noise may occur.
The capacity required for the Communication Unit internal power supply,
can be obtained using the following formula:
Communication Unit internal power supply current
= Communication Unit internal current consu Sum of I/O Unit
Interface current consumption
Note
The above formula applies when a voltage of 24-VDC is supplied to
the Communication Unit internal power supply terminals. If the
supplied voltage becomes lower, the current consumption will
increase. Select a device for the power supply that will allow a degree
of variation.
When selecting a power supply, take inrush current into
consideration.
The following OMRON products are recommended for the 24-VDC
power supply:
S82K-05024:
100 to 120/200 to 240 VAC, 50 W
S82K-10024:
100 to 120/200 to 240 VAC, 100 W
S82J-5524:
100 to 120 VAC, 50 W
S82J-5024:
100 to 120 VAC, 100 W
For details of the I/O Unit interface current consumption for the Units,
refer to page 30,
I/O Interface Current Consumption
.
Select power supplies for the I/O Units that are suitable for the load currents to
be used and the Units’ internal drive currents (refer to page 53).
