Note
Master Unit
An OMRON S82-series Power Supply for the communications power supply
for CompoNet Slave Units is recommended.
For details on current consumption for each Unit, refer to Appendix C Current
Consumption Summary.
A 24-VDC power supply is connected individually to each Slave Unit. Power
does not need to be supplied to the Master Unit.

(1) For network power supply Slave Units, the external I/O power supply is
(2) Use a power supply with sufficient capacity considering the inrush current
• Input Bit Slave Units:
• Output Bit Slave Units:
• I/O Bit Slave Units:
Communications power supply current consumption = Bit Slave Unit com-
munications current consumption + (Bit Slave Unit input current × number
of inputs used) + (sensor current consumption × number of sensors used)
Communications power supply current consumption = Bit Slave Unit com-
munications current consumption + (actual load current × number of actu-
ators used)
Communications power supply current consumption = Bit Slave Unit com-
munications current consumption + (Bit Slave Unit input current × number
of inputs used) + (sensor current consumption × number of sensors used)

also provided through the Flat Cable from the communications power
supply connected to the Master Unit or the Repeater Unit.
When calculating the output current of the communications power supply,
always include the external I/O current consumption and actual load cur-
rent for network power supply Slave Units.
For example, the power supply current consumption for Bit Slave Unit is
expressed by the following formula.
