Specific Example Section 2-2
Note The above formula applies when a voltage of 24 VDC is supplied to
the Communications Unit internal power supply terminals. If the sup-
plied voltage becomes lower, the current consumption will increase.
Select a device for the power supply that will allow a degree of vari-
ation.
When selecting a power supply, take inrush current into consider-
ation.
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 9, 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 41).
• Connecting I/O Units to I/O
5. Set the DIP switches for the Communications Unit, Analog Input Unit, and
Analog Output Unit.
Note a) If a DeviceNet Configurator (versions 1.11 and later) is used, the
input range for Analog Input Units, the output range for Analog
Output Units, and I/O Unit interface error output (high-clear output/
low-clear output) can be set via the network. When setting from
the Configurator, use the DIP switch to set the Software Setting
Enable/Disable setting to Enable. For details, refer to 5-1 Analog
Input Units and 5-2 Analog Output Units.
